Wow, this post makes me sad! Dh and I are the other way around, I am the one who loves to camp. He just comes along for the good food I cook to bribe him along! As others have said, sounds like camping is not the real issue here. Really, sleeping on the couch because you mentioned camping?
Judging by your sig, you have kids? I'm only assuming that because you purchased a sizeable bunkhouse tt. If so, why not leave wife home, go out and have some fun making memories with the kiddos? Sorry but marriage is give and take, sounds like it's her way or the highway. You seem to be a concerned husband by posting here but remember it's your life too!
