Ex boyfriend..new girlfriend?

So me and my ex had a real rocky relationship..we were together two years.. i'm pregnant. we broke up and I moved out..within a WEEK he had a new girlfriend. I can't seem to stop contacting him..I'm just so hurt, and I really WANT him back and I want to work on a better more healthy relationship. Any advice? I know he still loves & cares about me..he tells me so..help, i'm so torn. judgements are unnecesarry, they really do no good. i don't want to hear he's an *** or anything because he's truly not. just advice please.i get this crazy urge to text him!!
