You payed $30,000 for your daughter to marry a guy who’s life plan was living in a van? Ok, well we won’t get into that too deep. It’s their dog, if you want a dog, you have to take care of it. In this case the dog is theirs so they need to take care of it. You should feel more guilty about paying for the wedding. Your daughter is taking advantage of you. Tell her to grow up and get a house if she wants pets. The dog is not choosing to live “van life” aka being homeless. Please stop giving this girl everything she wants, that’s not a relationship. You are not bank of mom.
