WR, Some MLCers don't hook up w/OW/OM. Some are content to live a lonely life and stare at four walls. Now, I will share this w/you...my xh told his family the same that you h is telling his family about no ow or interest in seeking one out. However, my xh was having some type of relationship w/his ow (deceased wife) for about a year or so before he ran. So, take that be info and treat it w/a grain of salt.
Your h is reconnecting w/G because G is pretty much single again and MLCers will gravitate towards separated and/or divorced people. "Birds of a feather, flock together" as they say. Oh, yes, they do love to provide advice on what to do when it comes to divorce and separation of others going through it. Like they have a clue. LOL!
Of course it's moving slow...the process takes time and he thinks because he snaps his fingers it should be over done with. Too bad, butter cup...divorce is not like elopement. It takes time and there are a lot of variables that need to be considered. He's going to find that life didn't turn out the way he planned or thought it should be now that he's on the street.
WR, you are doing great. Keep up the good work.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
