Friday Blahs

Is it abnormal/unhealthy that my mood is so affected by my husband? Case in point, today is Friday and I couldn't care less - because he works this weekend. If he were going to be home I'd be working on a grocery list, planning the wonderful things I could cook for him, and touching base with our friends to see what's going on tonight. But instead I have a headache and am thinking about staying in my pajamas all weekend. Does anyone else do this?
