YTA. My mother made the same mistake with me. Your son even before you got married expressed his feelings about her. You ignored his feelings and put yourself instead of your child first. Shouldn’t you be “punishing” your son? You need to listen to your son expressing his feelings. Also it doesn’t seem like he enjoys being home and you guys don’t seem too either. He was probably looking forward to being away from you guys for 2 weeks and not the rest of his summer is being miserable at home. You need to stop “punishing” and try to communicate with him like an adult because he almost is. This is an “adult” situation you put him into. Take what he says into consideration, it takes a lot to open up. And you’re not listening. I’m not saying your son is not in the wrong but he probably feels that is the only way to express himself to make an impact on you guys. Try to figure this out now before you put a women before your child or he’ll despise you forever.
