I'm guessing u was hurt by this guy alot at the time he left u? and he didn't keep in contact?
mayb u feel like letting him know how much he hurt u. In what state he left u, For him to feel ur pain. and then for him to tell u, he still loved u and always thought of u while he was married to his wife?
what ever u wish to speak to him about. It wont achieve anything now. Only thing it will probably do, is bring back old sparks.........ur married and his married.......if his happy or not, is none of ur business. Only thing important is ur happy in ur marriage so dont do anything stupid tht u will later regret.....
once the doors r shut keep them shut!
