Mothers Day dillema....?

My husband asked me if I wanted to go OUT-OF-TOWN to visit my mother-in-law on Mother's Day. I told him if I had the choice I'd rather stay home & relax. I am a mother of 4 & Sunday is almost my only day off. I hear him call & tell her that we probably wouldn't make it, but maybe we could meet one day during the week 1/2 way for dinner. That sounded great! I thought it was a plan. Tonight he keeps asking me if we're going to his moms tomorrow. I said I thought we had a plan to meet her during the week & he said real snotty "Fine, it seems like you don't want to go tomorrow, so I guess we won't." Now, he's all mad at me. I'm not going to be able to enjoy my mothers day now anyway, atleast not w/o feeling guilty. Am I being selfish?? What would you do.

To top things off, my oldest daughter called me tonight & invited me to her house here in town for a grill out & now I feel like I can't go visit my own daughter on mothers day because I didn't want to spend all day driving to visit HIS mom. Ugh. Why does this have to be so difficult. We have a 7 & 9 year old together & I guess my feelings are hurt that he's deciding how I'm going to spend my mothers day.
