First i heard from the kid that babysits his son that his son doesn't know, he thinks i just work a lot. But now a few days ago my ex's brother in law text me if everything was ok. I said i was fine, he asked why i wasn't at Thanksgiving as my ex told everyone i was in utah with family (i ended up there but that wasn't my original plan i was supposed to be with his family). i told him we split a month ago and he seemed shocked. He thinks my ex may be reconsidering then if he's not wanting to tell anyone. But at the same time i haven't heard anything from him in like 20+ days. The whole thing is weird and making me sad. He has commitment issues and im pretty sure thats why he ran. advice, suggestions?
