Ex Hoovering?

Ex husband came to visit D at my house, whom he hasnt seen in 7 months. Re-cap-we divorced a year ago and I divorced him, although did not want to. He immediately moved in with a much younger woman and her 2 kids (her neice and nephew actually) and seemed happy as can be. this past weekend when he came to see D, we went out to dinner and these are some of the things he said
" my life is so exhausting", "I need to be in a padded room", "there is so much going on". I asked him if him and g.f's plan was to move and he answered "My plan is to move closer to you and D". He complained about all of the activities he is constantly driving kids around, church, etc. He said work is his "escape" from life..Funny, i thought all was happy in la la land.
Cant help but feel a little satisfaction. I also recognize I still have glimpses of feelings for this guy
what do you think about the info he is sharing with me?
