OK I can honestly say I've made the biggest mistake in my life. It has almost been 2 years since I have kept a secret from my brother. My brothers best friends & I share a child together. Im tired, stressed, scared, dissapointed & hurt. Everyone knows how the story goes, one thing lead to another. We thought it would never come up again this was a mistake life goes on. Well next thing I'm with child. He assured me that he would b there for the baby. I Was fine with that. At the time I had no intress of being in a relationship with him. I Explained that to him. I Was really ashamed of what I let happen. We remained being friends during my pregnancy just as before. When our child arrived it brought the two of extremely close. We wanted to b together. We both were scared due to our situatión. He pulled away from me, doing things that is not of him, he started arguments with me started seeing other women. I Feel he was afraid to love me Beàuse he feels he would have to choose between me & my brother. Making me angry with him would b his way out. Well during his time being with other women he got back together with his x. I try to act as if I'm strong enough to deal with it, but I'm not. I feel he wants to b with me but heS afraid of losing his best friends & I'm afraid of hurting my brother. He told me we should just leave it alone, focus on taking care of the baby. I've tried to do that but there's a part of me that does not want to give up. Should I trie to b with him or leave it alond?

It sounds like he is frustrated about his feelings and dealing with the situation in an immature way. He is not facing reality and that is exactly what you should be doing right now, facing the reality of caring for a baby which should be your first priority.
