To stay or be a single mom

Im 27 and my bf is 30. I'm only 6 weeks and 2 days pregnant and my bf is already disrespectful and emotionally abusive towards me. His mom even blames me for his depression and him contemplating suicide sometimes. He blames everything on my hormones, but even before he blamed everything on my so called pms. Him and his mom even brought up a abortion just so nothing brings her son down financially if I become a single mother and he ends up owing child support. Talk about selfishness even though they both say after they care about the child. To be honest I would hope the situation would change for the best, but with the wishy-washy ness I don't trust him. The child is more important and I'm keeping it no matter what. I was just wondering if this could just be him possibly worrying about being a father or something. As you can see I'm all out of answers and any advice would be much appreciated wether you have been in this situation or not. Thank you
