Personally, i'd let time heal you. I know it can be hard, but if she wasn't fully invested in the relationship in the first place, then she probably won't be the next time. From what i've read it sounds like she's leading you on alittle, and she may be unsure of what she wants. I'd cut contact so she doesn't think she can use you as a rebound in the future. You never know that may help her figure out what she wants too. Keep your head up, it'll get better with time.

I was in the same situation as you last year the girl I went out with although we were together for 4 years was really bad for me and I was always stressed out and not happy and even to this day I still miss her BUT I cannot stress the importance of not contacting her if you were the one who got dumped. Block her off everything and don't contact her. Since you broke up have you spoken at all to her? If yes then go on a 30 day no contact cycle even if she calls ignore it, if she texts ignore it honestly it will drive her crazy that you're not replying. If you want her back don't contact her for at least 30 days then if you still want to then drop her a text and take it from there.
