In-laws coming over for Valentine's Day?!

Jamie
My mother in law invited herself to our house tonight for Valentine's day! They were going to keep our 5 yr old while we went out tonight but plans changed & we are just staying in. She said they need to leave their house tonight because her other son & his wife need the house to themselves for their first Valentine's day! I agreed but told hubby I'm not ok with it & hes going to cancel... But am I wrong for being upset? I kinda feel wrong but seriously I'm entitled to celebrate this day too!
