From my perspective, you have it good. I have just left my husband because I have reached the limit of my endurance with his adult daughters living here rent-free and mooching off us. If you love your husbamd, try not to leave him over this. It could be much, much worse. Just never let her move in, under any circumstances, or under any pretenses - if he can't set limits about a hot tub, he won't set them on anything else either. Good luck.
