Dilemma

So I'm on a dating website...  I'm still not over my ex-husband and I have a wonderful older man who thinks I'm "gods gift" so what am I doing???  I was single for 7 years before I married my ex and that turned out to be a nightmare.  I need to reconcile in my mind that I'm not meant to be in a relationship - I'm just not good at it.  I should go back to the therapist and delve into why I'm so bad at relationships.  I think I'm a good mother, sister, friend but fail at the wife/girlfriend role.
