I can't see that the kids would benefit by exaggerating or making up their complaints. They get their lives rearranged and taken from their mother which is never fun. Kids know what "fun" is and when a loving person is kidding, etc. Doesn't sound like your boyfriend is a good choice if you want to care for your children too; I'd be looking at him differently and reviewing how he treats/cares for me. I married my husband after first looking at how he treated other women; his ex-, his mother, my mother, me, etc. He has three sons and gets along well with them, I would have thought twice about him and the future of our relationship if he hadn't.
