Your thoughts?

So the father of my child and I have been through a lot. He used to be in LOVE with me and I only saw him as a friend. Eventually I started to like him and we ended up having a baby. But keep in mind, I was his first everything. When I was pregnant, I found out he cheated on me (not physically. That I know of) after that, we went downhill. Months later, we tried working things out but it just never works. Hes constantly getting upset about random things. Hes pretty much told me that he wants to mess around with girls because he didnt get the chance too. He acts like he still wants me though. Says he loves and cares for me. Sometimes affectionate in front of people but he wont be with me! I just dont get it!! I'm still so in love with him and for some reason, something is still holding on to him. I just dont know want to do. I dont want to wait for him to do whatever with girls..but its also so hard to move on. I've gotten so depressed and I feel like I cant ever be in a good mood for my daughter.
