How do I begin to make a decision between two people to have a relationship with?

Married to Dan for 5 years. He would get drunk a lot. Felt like something broke inside of me to keep dealing with it. Am not sure if the damage can be repaired. He aplogizes, says he loves me & has stopped drinking. On some level I still love him and don't want to hurt him.Met Ray a year ago. Feel alive again. Have told Dan about Ray. Am "in love" with Ray...problem is he is with Tracy.He went back & forth between us 2x.They got divorced but still live together...he is in the process of moving out of state without her and wants me to go with him to have a "fresh start" for both of us. He says he loves me & apologizes for hurting me & wants to "make things right by me". Don't want to hurt him. Don't know what the right thing to do is.
