Should I go? (Read description)

My husband works at a school and they’re having a holiday party at a bar. I really do not want to go. At all. He keeps pushing and pushing to get me to go but I really don’t want to. I don’t know anyone, I have nothing nice to wear due to huge boobs from bf-ing and needing to lose some lbs from this pregnancy. On top of all of that, I would be sitting around watching people drink while I can’t because I ebf- not pump, and my daughter nurses way too frequent for that to happen. What would you do?
