I love him but I don’t know what to do anymore...

I’ve been dating this guy for a while now...we’ll not anymore. When we first met we were messing around with other people and we weren’t looking for a relationship, especially him because he had just going out of a 6 year relationship/engagement a couple months before I met him. We were friends for a while and then we started to fall for each other and things got serious but we still emotionally weren’t ready for a relationship so we just took things slow and didn’t force anything. Next thing you know I’m talking to his parents and their excited to meet me and he’s meeting my dad...2 days later he breaks up with me and I didn’t know why and he wouldn’t tell me until a week later. It was because he thought I was ready for a relationship which I wasn’t and neither was he, so we talked about everything, worked it out, and decided to be friends and when the time was right we’d get back together(this was the second time he had broke up with me over something dumb). But He was being confusing and mixing friendship and relationship together. Eventually started to see things that he was use to in his past relationship that he needs to get out of like breaking up and coming back and not communicating. I told him that once he’s ready for a relationship those things are going to cause issues and he needs to work on them(this is after we got into a argument after he hung up on me in the middle of me speaking because he didn’t want to hear what I had to say). So eventually I ended things for the first time and I’m trying to be friends with him but he’s acting so strange now that I don’t know what to do. It’s like I broke up with him once and everything changes he’s a different person and now he doesn’t know how he feels about me and I just don’t know if I should let go or fight for the friendship...I keep telling myself maybe his acting strange because his relationship ended a year ago around this time but something is telling me it’s not...
