I feel I need to leave now but he’s making it impossible to leave

I get annoyed with the person I’m with I tried to leave him but he started crying with his eyebrow twitching and he told me that he would change and he told me don’t throw him away like trash like he doesn’t mean anything . He would be more understanding with my schedule and he wouldn’t stress me out anymore but already a week in he’s showing little signs that he hasn’t changed. First sign is answered an unknown phone call and he put it on speaker and it was his ex and she was saying some explicit stuff and he’s somewhat laughing and then he told her I was there and he told me to say something to prove I was there which was embarrassing. Last week he told me he wasn’t going to force something I wasn’t in the mood for and then today i told him I wasn’t in the mood for anything sexual and he wouldn’t stop asking for head even though I told him I was not in the mood and his eyebrow started to don the twitch thing when things don’t go his way. The understanding we had about my schedule is almost forgotten. I told him there will be a week where I’ll be busy with work and one work where I’ll have more time and at first he was understanding about that but now he’s pressing me about time when explain it to him. I want to leave but the way he is, it makes it impossible to leave because he’s going to call me from different phones and that’s going to make things even more stressful than now. I’m tired because he also thinks him spending money is going to keep me
