Like elizabeth said, focus on God right now. You can pray for your boyfriend in jail however you like. The decision you made to move away from him is something that will affect if you wanted to visit him and wait for him while he's in jail. You could move back if you felt that's where God wanted you; that is if he really changed like you believe. If you are wondering whether or not to go back to him and wait, ask people he knows whether he really changed. A lot of times we see the best in people if we are physically close to them and share a lot of ourselves with them. But you're number one priority is and always has been to be in a right standing with God our Father, which can only happen through what Jesus did for us. Remember his sacrifice of pure love for you and you're well being and cherish Him above finding the answers that will quell your confusion. God brings comfort, God brings peace, God our Father gave you your greatest blessing, your little one. I pray that a church around you will look to you with compassion and come around you to your aid in this time of turmoil. Go to a church around you and find an older woman to talk to. I pray your child will be loved with the same love that you recieved when you were adopted into the family of God.
