opinions?? / online relationship

this story is probably way different from others but i just wanted to see if i can get anyones advice or opinions on my situation. i will try to explain, in detail, the best i can from the start. (this will be very long so if you like reading then this could be for u haha) okay so 2 years ago (during covid) my cousin asked me to play roblox with her and so i was kind of reluctant because to me the game seemed stupid but eventually i downloaded it to play with her. i thought it was really only for kids but i noticed that there were so many different kinds of games that anyone could play it. anyway tho, i got roblox to play just with her but i started actually liking it so i started playing it by myself too. one day when i got on i decided to join a driving game because those were always my favorite types of games. i played for a while with other random ppl in the server and eventually this one person joined. i didn’t know who he was but it started off as us racing each other. i think we started a conversation just by asking each other if we wanted to do a different race or maybe it was because we were both being really competitive. he was really funny in the chat and had a great sense of humor. i noticed there was something different about him and i just loved his humor. that night we ended up playing until like 2/3 in the morning. i texted him after the game (which i usually wouldn’t do but i rlly did take a liking to him). i found out he had a girlfriend irl but i thought nothing of it because it’s not like i know him irl or anything. as the days would go on i would continue playing with him and join his games sometimes. eventually i found myself getting on literally to see if he was playing. now, this one time we were playing and i found out that him and his girlfriend were taking a break for whatever reasons. after that we decided to play a different game together and somehow it lead to me telling him i kinda liked him (again ik it may be stupid bc it’s someone i’ve never even met or anything). i was so scared to see how he’d respond. i thought he was gonna block me or delete me or something or simply think it was dumb to like someone i’ve never met. he responded really well and said he liked me a little too but said him and his girlfriend were most likely going to get back together, which i totally understood. i would never get in the way of a relationship and so after that i still kept it friendly. like i expected, he let me know they got back together. we still played together but kept it all friendly ofc. weeks went by and we were still playing together occasionally (also, i never thought anything of him and his gf bc i knew i had no chance since i’ve never met him or anything) but after those weeks passed, i did end up getting his number. around this time he had told me that he wasn’t with his girlfriend anymore. he opened up about that over text and the more we played, the more we would talk about new and different things. we started texting a lot more too. we even became flirty at times. i knew what he looked liked and he knew what i looked like too. after texting a ton we started sending voice messages (really only because he wanted to call and i wasn’t comfortable with that since i don’t really have my own space/my own room) but he actually respected that and we kept it at voice messages. i started to really really like him and i knew he could tell (even tho i tried to hide it). fast forward to when he actually asked me to be his girlfriend. before this happened we talked about being in a relationship and seeing if we could make it work and after long conversations we agreed to give it a try. we had so many heart to heart conversations, funny conversations, and serious ones. we got to the point where we said i love you to each other and stood up really late just playing roblox together having a good time. a year passed and in 2021 we were still together. there were times i was worried it wouldn’t work (bc of the distance and everything) but as each day passed he really showed me that it’s possible. covid was a really lonely time for me and i absolutely loved having him. fast forward again, when school started up again for me, i made a friend- who now is my best friend. she was there for me since the beginning of the year and didn’t know about my relationship. so, i started talking to a boy in school. my friend knew about the boy in school (but again didn’t know about my online relationship). i knew it was wrong of me to talk to him and i really don’t know why i kept that going but i did. we were in the talking stage and almost had it go further but it didn’t work out. i still feel guilty for talking to him and almost having that going further knowing i was in a relationship. as school went on i only focused on my classes and not boys or anything because i was still in that relationship with the boy no one knew about. summer of 2022 came and i became even closer with ~online boy~. we were still together but this summer was different. we’ve been more open then ever with each other and i got him to open up which definitely made us closer. we’ve had long long conversations and exchanged pictures. so, i’ve finally made it to now. now, we are still together and closer then ever! now the thing is, we still can’t meet in person or anything since i’m not even old enough to figure that out yet anyway which i’m upset about but not too upset since we’re really making it work. i’ve also noticed him trying more (because he admitted that he’s bad with texting) but i definitely noticed a good change. my best friend doesn’t know about him at all still and i really don’t know if i should tell her or not. she’s pretty.. hardheaded.. and i feel like 1) if she knows i’ve been with him for 2 years and didn’t tell her she’ll be upset that i kept that from her and 2) she knows i was talking to that boy in school so she’ll probably also be upset with the fact that that almost went somewhere while i was literally in a relationship which is 100% reasonable because i know it was wrong. if i don’t tell her i feel like it’ll be a weight on my shoulder but i don’t even know how i would go about that conversation. (especially i’m not AT ALL good with confrontation). no one else knows about us being together and id love to tell people my story but i feel comfort keeping this to myself and i don’t know why. i truly do love him and i’m hopeful for the future because of him but i just wish i had someone to talk to about this/him. i’m really sorry if this story is confusing or all over the place but i just wanted to get it out there and maybe get opinions if someone was even willing to read all of that. if someone can respond , or even read this at all, i would be really thankful. i also tried to get in every detail because it’s been a story i’ve been waiting to share for a WHILE :’) lmk what u guys think <3
