What do you think?

So I'm pregnant and the guy I'm pregnant by we haven't been getting along lately and plus he still questioning if it's his but he hasn't really been here hasn't been to any of the doctors appointment and yea. Now I have a friend I been seeing way before I got pregnant and he is still around we talk every day and I'm not going to lie we still hook up here and there and he knows I'm pregnant. He checks on me we literally talk every day and he is the sweetest but we never established what we "are" before I got pregnant. I know most dude would leave but he is still here and today he offered to help me with my car because it broke down. Now the dude I'm pregnant by every time we talk it ends in an argument and he doesn't check on me if and when he does text me it's always "wyd" and never how are you how are things going. I have been depressed lately because I feel like I'm going through this alone. But what do you guys thing and please don't be rude
