trying to move on from a toxic relashionship

ad dated a guy for a while whom i felt comfortable with and loved dearly and thought we were both on the same page when it came to sex (important to know i was introduced to this guy by a mutual friend)

i had speciffied i want to wait until marriage and he seemed ok with it however he was making jokes behind the scenes of discusting things he wanted to do and when i conforted him about it he onky told me i was over reacting and i wasnt hearing his side so i was acting "toxic" and after hearing that i was made to feel like it was my fault

i later realized that the friend whom told me about what he was saying about me was getting hurt by him and was being threatned same thing goes for friends whom told me i shouldnt listen to him and break up with him

after this it was over i ended the whole thing and it was suprisingly not that bad i was sad and scred and i still kind of am ik hes tried to hurt others in the past however what hurts more is the friend whom was getting hurt still choose to be friends with him and hang aorund him even after i explained why its not ok. she tried telling me i was over reacting and she didnt know why i acted so bothered by it but it makes me mad becuase ik she always tries the stupidest things to get my attention and come up to me for the dummest things. ik it may sound like she may be scared of him but i made sure to talk to her, her mom and school to make sure she can stay away yet she chooses to still have her arms aorund him.

idk why im writing this the more i talk about it and think about it i realize that they guy i dated the only thing i miss is having someone ig that cuz he alwys told me he was the best ill have and made me out to be someone who is so deppressed i cant look out for myself however i try to remind myself that the moments are miss are when others where there to not when we were alone and i was crying or he would do "tests" to see if i was loyal

ig i need some opinions all my friends say i made the right choice but i still feel sick inside its weird that i from the beggining i felt like i was convinvign myself i was in love but something always felt wrong and i just want some advice
