Not pregnancy related but I need some help from you guys!!

Am I old or is it not fun to go out all the time and stay out all night. My husbands family wants to go out to someone’s house every weekend and drink like animals. Me being pregnant I would have to drive, every time. And honestly I don’t think it’s healthy to drink that much at least once every weekend. Maybe I’m a bitch.. which is what they think. Or maybe I’m a party pooper but what the fuck... like it’s not even fun watching drunk people karaoke all night. Yea I love all the kids get to play but it’s like 2 of us sober taking care of them and I’m sleepy and I’m just over it. Like they hate me now because I never let him go anymore but every once in a while and it may be their culture and not mine but damn. Your culture just drinks like fish? Let’s go to the park, let’s do a cookout. Why all the drinking... you’re not making my husband a drunk ass. Nope! Am I being a bitch? Please be honest because I feel bad that I didn’t let the kids go see their cousins tonight or lately but damn it’s like why do we need to get drunk to hang out? And these people are all ages, from like 20-40... it’s not just the young ones it’s everybody.
