Don’t feel like my boyfriend loves me anymore.

So my boyfriend (M20) and me (F20) have been together for 1 1/2 year and are having some problems. The thing is, lately I’ve been feeling that he is not in love with me anymore. Like he is not even attracted to me. Therefore, I have been feeling a little down around him. For the past weeks I have been trying to kiss him but he seems to avoid the kisses or give me the «grandma kiss». I have tried to dress up nicely, make dinner, tell him how much I love him, leave cute notes at his gaming pc to try to spark up the romance a little bit. but he doesn’t seem to give any response at all. Now, he is a gamer and he likes playing with his friends. Last weekend he was gaming and I was in the same room as him minding my own buisness. After a while he turns around telling me that he and his friends are flirting with a girl online for fun. I did fint it a little wierd but I just gave an awkward laugh and said «have fun». Boys will be boys. After i had been sitting there for 3 hours he started to ask if she could add him online so he could send her memes. (Memes is his way of communicating with people online). At this point I was very uncomfortable. Why did he say those things when I was in the same room as him? The thoughts of he not loving me anymore started to take kontroll over my brain. (Yes, I do overthink things) So I left the room crying. He followed me and I told him how I felt sitting there with him flirting with another girl. He said it was nothing like that and stayed with me till I started feeling better. Then I could here his friends wanting him to come back to play so I said he could go. He went back and stayed up till 7am. The next morning he acted like everything was alright but I didnt feel fine. Nothing changed, I still felt like he wasnt attracted to me, he still didnt want to be intimate, he keeps playing with his friends and this girl. A few days after he once again started telling me how amazing it is to play with those people online. I said I didnt want to hear about it since it is still a sore spot for me. He got a little bit annoyed but brused it off. That night when he ashed me if i was okay I said no. I told him everything about how I was feeling and we got in a really big fight. He didn’t understand the impact the girl had on our relationship and got angry. For him it was nothing, he couldn’t care about her, he was just having fun with his friends. I told him that understands and that the girl is not the main problem. I needed those little romantic things back in our relationship so that I wouldnt react this way if he is talking to other girls. It would be nice to once in a while get a compliment, a kiss, a cute note, or just anything that tells me that he appreciates me. That makes me feel wanted and loved. After the fight we talked and we both said we would try to be better. Me for instance is trying to be less sad and angry. Now a few days have passed and I still dont feel like much has changed. I still dont feel like he is attracted to me, He gave me one compliment but it felt super forced. We are still not intimate. He goes to bed at 4-6am and I wake up at 7-8am because I have to study. He wakes up at 3pm, we have dinner, watch a movie (like everyday), then we do our separate things in the same room. This is not enough for me..... I need the little romantic things, just a note, or a genuine compliment, or a kiss but NOT a grandmakiss. An I love you kiss. If things dont change I dont know what to do. I know I dont want to keep feeling that I am wasting my time with someone who dosent love me anymore. Any advice?
