We are guests staying with my MIL and her girlfriend. Also living here is SO’s brother. Said brother (Dylan) is a know it all, bum, doesn’t do for anyone. We want to take the in-laws out to dinner but don’t want Dylan to go. Honestly because I’m done doing for him when he doesn’t appreciate it or do for anyone else. He works and pays no bills here so he has money. If he paid for himself it might be different but I just can’t stand to keep doing for him. We’ve bought dinner here a few times and he never appreciates it. Are we wrong?
