SS has a girlfriend and BM is supposedly losing her mind
A preview of a future toxic MIL:
One SS (approaching 17) has his first girlfriend. We didn't see him the last weekend because it was homecoming, so he was off at events with said girlfriend. Other SS is anti-social, so he came to our home and was lamenting to DH about how his brother was staying out "late at night" with this girlfriend whom anti-social SS called a wh***. DH told him not to use that word and SS replied, "well, mom thinks she is. She's upset that [brother] is out all the time with her!" Mind you, SS with the girlfriend has been enmeshed with BM since the divorce (likely before the divorce). He was the one she confided in about how exH#2 (aka former stepdad) "wasn't the man she thought he was" and also about how she had to dump her previous boyfriend because he "had an alcohol problem", so I'm sure BM is freaking out at losing her precious pet. This SS has friends who are mostly okay, so I doubt this girl is truly a wh*** as BM has dubbed her. Also, if BM doesn't want him staying out to all hours with girlfriend, then maybe she should tell him he can't...that said, I think BM is often out with her current boyfriend, so how does she know where SS is or when he comes home.
