Glam, Hope you are feeling a bit better this afternoon. This leg of the journey is the hardest part. Love him from afar.
Here's my take on the receipts, and it's just my opinion, I don't think your h is out playing games at the gym. I think your h is so screwed up w/depression, he's going out at that time of the morning because he can't sleep. If he were out exercising, he would have mentioned it by now. I think he tossed that comment in about the games, etc., because he knows you are up and going to the gym. Glam, it doesn't matter, listen and then let his excuses fly out the window. I just do not believe him at this time.
As for you my friend, lots of liquids, rest and comfort foods. Let him go for a while and concentrate on yourself and your children. He'll catch up if he really wants to. Whatever you decide to do, Glam, I'm there w/you 100%.
Take care of yourself...you are a valuable cyber family member.
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.
