I didn't want children and now she wants me to move in with her and help her raise the child and eventually marry her. But I don't want to marry her. I don't love her. I'm doing all I can to prepare for the child, and I'll support it and love it, but I can't see doing it with someone who will probably hate me for not committing to her. I've been wanting to date after our breakup, but I haven't because I feel guilty dating someone else when I'm about to become a father for the first time.
Guilt is no basis for a relationship.
Give her what help you can, but your commitment is to the child, not to the mother, and you should feel free to date. Dear Mr Blue, I've been with the same woman for almost 20 years, married for 15 of those. She is incredibly jealous of my friends, both male and female, and has harbored suspicions about me from the start. I've always had fantasies and even flirted a couple of times but never came close to having an affair. She is a controlling type, and my anger toward her is increasing daily.
