Maybe she's trans and it's transphobia instead? Not that it would be an improvement; I'm wholly team DTMFA.

I'm also wondering about the layout of the place - LW says it's small, and BF wants her to give up her home office so his kids can have a bedroom, but also they'll have to sleep apart? Does that mean she has a guest room that could theoretically be turned into the kids' room if they were sleeping together? Or would he be sleeping on the couch and convincing his kids that he does it every night? I'm so confused.
