shes going through a divorce and she met a guy recently. after a week she stopped talking to him as she felt it was wrong because the divorce was not finalized and husband was still living in the home. Husband has moved out and still in the process of the divorce but she cant stop thinking about this other guy and cant decide whether to just forget about him or give him a chance. Also she has not had sex in a few months with anyone. Any advises?
