I can't take this anymore

I'm so disappointed in myself. I have allowed myself to talk to someone who is so incredibly disrespectful towards me. Apparently I killed his vibe and this is like the 4th or 5th disagreement we have had since Friday which is never good. I honestly don't even know what I did. All I ever get told is I don't listen or I ruined this or I did that. And I ask for what I did and I get told nothing so I never have any clue. I'm so scared that I have lost him tonight and I know it shouldn't be a bad thing that he would leave but I have been talking to this guy for almost 2.5 years and I'm in love with him. When I love ppl I love them very hard. I have tired telling him how he makes me feel and I've old him that hoe he treats me is the reason why I go and form relationships with other ppl because they give me the things he doesn't (I'm 17  and like we're not dating and I'm not just like talking to random ppl I just want someone to be able to chill with) everything is fine when he is happy but if he isn't then I'm in the wrong and I'm a horrible person. How can someone who loves me do this to me. How can they hurt me all the time but ask me to change? I don't know if I should talk to him or try my best to leave. He was the last person who I thought truly supported me and if I have the support system taken away from me then I don't know what I'm going to do😭💔
