Completely torn

Hey!

Okay, extremely long story short.
I began dating this guy in October and it was love at first sight, from both parts.
We began seeing each other very often and he texted me a lot, gave me compliments and yeah basically acted like the perfect guy.
My mom wouldn’t accept me seeing this guy, so I moved out of the house for like two moths, and didn’t speak to my entire family during this time.
During this time I still saw the guy, and he was still perfect to me. But I was so unsure whether he was sincere or not, so that and the fact that I didn’t speak to my family because of him, lead to me “breaking up” with him a few times. But we always got back together. And now I realize it was completely stupid of me thinking he wasn’t sincere and totally dedicated to me…
But one day I didn’t feel like I could bare the feeling of being insecure about if he meant what he said, and I broke up with him for good. But like twenty minutes after I was regretting my action.
Then we met at a party and we got back together, actually declared us as boyfriend and girlfriend.
Then the next day he says he can’t do it, because he can’t trust me.
We have then texted a couple of times, but mostly me being confused over his actions.
And for two weeks ago I met him at a party again, and we talked about it and stuff… He promised to text me the next day, which he didn’t. So I just texted like: you did again, not keeping your promises. And he answered just like “what?”. Apparently he got so drunk at the end of the evening so he didn’t remember saying he would text.
And that was when I began my ‘no-contact’ period, 50 days. The problem is we go to the same clubs a lot, and I’ll see him quite often… What should I do?
And I wanna get back with him, cause I really like him. Not even like, I feel like we had a special, like spiritual attraction and connection.
He is totally in a rebound relationship right now, she is the complete opposite of me, doesn’t have any of the qualities he seeks for in a girl, they began dating a week after we broke up, and the last time I met him he was like: I HAVE A GIRLFRIND. Like really trying to make me jealous, which let me to say that I’m also dating someone… Bad decision, I know!
But he acted like he still wanted me when I met him… And he has said things to me like: you’re the reason I give a f*** about anything.
But I don’t know what to do?
Btw. My mom and family totally accept him now and I’ve moved back home!

Okay, it ended up not so short after all!
Hope you guys can and will help me.

Best regards,
Isabella from Denmark.
