I don't know if my ex wants me back

I went through a really tough break-up lately, I was convinced me and my then-boyfriend were going to eventually end up getting married - we had talked about it and having a future together but some tough times came our way and he ended things with me.

I told him a few times how I didn't want this to end and we could fix whatever issues we had but he said I crossed a line and he couldn't look at me the same (nothing serious happened, we had a fight and he became very threatening so I pushed him away).

We had a talk tonight and I wanted a simple yes or no to if he still loved me.

He said he did but he wasn't sure if we were going to end up back together and that he needed time.

He said a lot about "time will tell" and "anything could happen".

He said I have a good chance and it's highly likely we'll end up back together eventually but I'm terrified of the thought of me assuming things are going well and he turns around and changes his mind or he finds somebody new.

He told me that isn't likely of happening but I'm paranoid, I don't want to be given any false promises and I even said to him if he can't give me 100% of an answer then I just can't do it and it would be too painful.

However, I can't help but wonder should I try to move on completely or actually take his thoughts into consideration.

I can't say I have ever felt about anyone like I have him and I know I'm young but he meant more to me than any possible hotter and kinder guy that could of walked in the room claiming to be my soul mate.

I'm very conflicted - do you think it's best I forget and move on for good or keep what he said in the back of my mind?
