Bright, I'm going to say something that you may not like, but it needs to be said. Your friends may be friends to you, but they need to stop telling you things about your h. It's not helping you one bit to hear all of this stuff. They may think they are being helpful, but the gossip isn't helping. You need to find a way to let them know that you don't want to hear about your h's antics.
I know you are trying so hard to figure him out, but you can't. He's going to do what he needs to do and it won't end until he's ready for it to end. It's very important that you keep the focus on you and your job search.
Again, I think your friends mean well...but I don't see where the info on your h was of benefit to you, if anything, it discouraged you quite a bit and brought you down.
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.
