Just shoot me

I spend like 3 or 4 days out of the week with my bfs family because he currently still lives at home. I wanted to go out tonight for once I got a babysitter and everything and he had a sitter for his kid too then last minute said he would rather stay home tonight with his family. Apparently his mom wanted his daughter home so he agreed and cancelled the sitter. Mind you I spend a lot of time here with his family and his child who I love but I wanted one damn date night. So I am sitting here in his living room while his entire family is playing a board game and i'm just pissed off. We haven't gone on a date in forever just me and him and once we move out which will be soon we will never be able to go out. Idk am I wrong here for being upset?
