Should I stay

I’ve been dating this guy for almost 2 years now…the thing is when we first knew each other we weren’t that commited cause he was still seeing his daughter’s mother and I was also with someone…because I was getting too close to him it seem like he was pulling back from me so we ended up drifting away…my ex surprised me for my irthday and next thing I know my guy wanted to engage to me…but I was avoiding him…I didn’t know this until after my bday thats when we strated to talk again…little did I know he was still sleeping with his child’s mother and mind you he knew that she was with someone else the next thing I know the girl was pregnant again with his child and he didn’t tell me this till after and he was actually going to propose to me…ow that the child is born he wants to play father figure…even though he told me he wants nothing to do with the child…I still feel that he would end up back with his child mother…if I see him today I wud\n’t c him back till a week after when I call he’s always busy or answers da phone as if I shudn’t be calling…he says that he wants to be with me but he doesn’t show it I really love him but I can’t take the way he treats me…
