Should I break up with him?

UPDATE: I did break up with him and I don’t even know what to do with myself

So me and my boyfriend have been dating for almost 8 months and things have been going well except for the fact that he is very jealous and possessive and always tell me what to do and what to post. Today I got fed up with it and tried breaking up with him but he begged and promised that he would change. I told him I needed to think about it. So i guess what I’m asking is for advice, should I give him a chance and see if he changes? Or not? Cause I am the opposite of him, not clingy, not jealous, not possessive and he is all that things. He is a wonderful guy tbh and he does nothing wrong except that and that’s just something that bothers me a lot and makes me frustrated. HELP
