H was staying out all night first on Mondays when he was staying at our apt supposedly working on the stove, but really meeting her. Then he started going to his karate class on Thursdays and heading to the apt to meet her then also, so two nights a week. I knew where he was, though, he was at our apt.
This staying out with friends is new. These friends are friends he had in high school, and stopped seeing when he was first with his XW 20 years ago. I've never met them, they reunited with him on fb. I thought at first that they were probably friends of OW also, but I know he didn't actually talk/hang out with OW in high school, they just sat at the same lunch table on occasion.
His buddies never said they would support the M. Quite the opposite, they support the A and have fully accepted her. She says by email "say hi to xxx" and they say hi back to her. One of these men is in his 50's and he still is not wise enough to say stay away... only H's best friend said he would support the M. Only one out of 4 friends.
