I can’t believe this is my life now

Our 4th night in our new apartment and he’s sleeping in his daughters room. He also broke up with me earlier. We also have a 3 month old baby. He made me miserable my whole pregnancy and cheated on me with two girls that I know of. I choose to forgive him. I don’t believe he is cheating but he’s so controlling and extremely jealous. He also has a warrant for his arrest. No steady job & sells drugs. Why did I set myself so damn bad man.
