advice or anything?

Jessica • Ok well I guess we are on our own baby😘
So I have not posted here yet. 
I was engaged and living in his home. I found out I was pregnant the same day I found him cheating on me. When he told his mother he did then she attacked me and I needed to leave our home. He has abandoned us and wants nothing to do with me or the child until it is born where he and his mother plan on doing everything in there power to take it away. His mother wants my child. I am scared and alone and not to sure what to do. But I am 30 and we tried for a long time for this baby, so my heart is saying don't ever let it go.
