I foresee trouble in your future. (No I'm not psychic, just observant ) If I was married and my hubby wanted to re-connect with an old girlfriend, I would not be happy about it. If you both were co-workers, or had mutual friends, I could see wanting to stay in touch, as you had other reasons to be in each other's company. I am one to want to hang on to people as I get very sad when I feel a connection with someone and they leave my life. However....no matter how involved I feel with someone in a romantic relationship, when it's over, that's it. No facebook, calls, email, nothing. It hurts at first, but I think keeping the person on the periphery of your life is just inviting future problems.
