It sounds like you are living a life of obligation. You feel like you are being a "good" son, but are you being a "good" husband? Your wife is putting up with a lot. While I understand your point of view, maybe you can make living there more palatable. Ex: have dinner on the couch and watch TV if you're tired and if Dad doesn't like it, too bad, so sad.if Dad is bored and wants you to entertain him and you're not into it, tell him to figure it out. Find a nice movie or documentary he can watch. You're doing a nice job as a son, but you also have rights. You two, while being kind people, are acting like doormats. I hope this helps open your eyes a little. My intentions are not to be harsh or unkind. Just wanted to put my 2 cents in and see if it may help.
