BD doesn't check up baby?

Amber

Okay so this is gonna be a little long so bear with me. My man and I had broken up last year for the majority of the year. We are now back together, and doing great. During this time, I had begun seeing someone else. We will call him G. When I began seeing G, I got on birth control to avoid a pregnancy so early in a relationship, I was already going through a custody battle of my 1 year old. Now in August, I found out I was pregnant. I of course told him, and I told my ex boyfriend (now together).

Fast forward, G doesn't like my boyfriend. He insults him in front of his face, publicly on facebook, and just tries being 2 faced with us. We had asked him to come over 2 months ago to figure out custody arrangements so MAYBE we didn't have to go to court. We agreed that we needed to come up with a plan. All 3 of us. Now G, doesn't answer texts, or calls from either of us. Since we spoke, I was rear ended badly, and had to be hospitalized. I am now a high risk pregnancy, and it seems G is no where to be found. We know where he lives, he knows where we are. He has social medias he can contact, and our cell phones. Should I keep reaching out to G? I don't want to take his son away from him, but I also don't feel he's making any effort to check on the babys progress. Any and all advice would help! Thank you!
