Wow, nothing from that man is going the easy route. I think for the MLCer, after the euphoric stage is over, they face a choice of better or bitter, to look inward or lash out. Your H most definitely picked the later.
Did you ever get the custody schedule figured out? If I remember H had the most cockamamie ideas about that. Your boys would be changing houses almost every day. Does the court viewable scheduling app have something to do with this part?
Are your boys enjoying summer vacation? I hope they are doing well, and of course you too.
On that note, it sounds like you doing great. Sense of humour back, invites coming your way, strong and healthy. Way to go HaWho.
Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
