Relationship

I live with my babies dad, I found out he was cheating on me with HELLA females. I was willing to give him another chance but he broke up with me. So we have been trying to make it work as friends for the past 6 months but it’s been nothing but hell. I want to move back with my family, which is 4hrs from here, but I feel so bad to take his son away from him cause he’s an AMAZING father. Idk what to do. I’m miserable but I want my son and him together.
