Beyond annoying

I'll be 36 weeks pregnant in 3 days. I asked my fiance multiple times during this pregnancy if we could go out to dinner just the two of us (we have a 2 year old and a 1 year old) but there is always an excuse of why we can't or why he doesn't want to. Today hes going out with a friend and spending time with him. Yesterday he had a friend over and they hung out. I have been begging him for months now to do something with me. But like I said always an excuse. Than he gets all ticked off when I confront him about. I feel like im over reacting but damn I want some time too. And it's not like we don't have a sitter to watch the girls. I just feel like im not a priority.
