I need advice?

I am back with my husband after being apart for several years.We have worked through our problems and get along fine.I am having a problem with the guy I was with during the time I was parted from my husband.This guy will not stop calling me his wife(we were never married).He emails me telling me he loves me and needs me and that our marriage is bent,not broken.I told him over a year ago it was over and moved on with my husband but this guy won't stop thinking I am his wife and we will be back together.my husband doesnt know about him and I don't feel the need to tell him about this because theres nothing going on between me and this other guy,what do I do?

You should talk to your husband about it. If he should learn that you're communicating with the other guy, it will look much worse than it is. Plus, the fact that you aren't telling your husband probably makes the other guy feel there is still a chance. Bring it all out in the open, ask your husband to help and shut down all communications with the other guy. If you have made a commitment to your husband, there is no reason to even having a conversation with him.
