Am I being anti social?

First of all, I’m 35 weeks pregnant and kind of just feel like a big blob... My husband works about an hour away from our house, and we have a friend who lives near his work (they’re married couple friends who have two little ones, very nice people).

Well my husband texted me asking if I wanted to drive over to their house for dinner tonight (I would be driving alone since he is already out that direction for work). I’m not working right now so I’m at home all day cleaning and able to rest thankfully but I told him I’d skip dinner tonight bc I don’t feel like it and he can have fun and enjoy himself... we have an early morning tomorrow (have to go to a family event at 9am that is two hours away and goes until 8pm at night...)

I feel kind of bad for skipping hanging out bc I have been doing that a lot lately but I honestly do not feel up to it, specially with a long day scheduled for tomorrow already.

He thinks I’m being anti social though, am I? Honest comments welcome ( but don’t be too harsh I’m hormonal 😉😜)
