WWYD?

If your boyfriend of 7 years, blending in his house for over 4 years- his kids no longer want to come to his house and their mother is telling him to “handle it” I cannot move out, nor do I want my kids to change schools again. His kids really don’t have a reason, I do not discipline them at all and me and my kids stay out of their way. It’s mostly the older daughter (15) but the younger one seems to be following that lead.
