Something tells me that there was some kind of problem between you two before he took this job. Does he work another job all during the week? This does sound like there is a serious problem. It sounds like he asked you about getting the job in the first place, and then he took it even though you voiced non-agreement. (?) That was a bad start. If this is a second job, why did he feel he needed a second job. It sounds like the two of you aren't talking things through.

You probably won't be able to pretend to be happy when you are this miserable about the situation. This is tough to resolve. It sounds like one of you is going to be resentful, whichever way you decide. That's a bad sign. You might want to think about marriage counseling.
