Husband at bachelor party for one of his best friends

I’m 32 weeks 3 days and my husband left for one of his best friends bachelor parties for the long weekend. I hate feeling grumpy about it but I can’t help it. I know he’s an awesome friend and has an obligation to attend but now I’m sitting here feeling sad like a little brat. He said there’s no guarantee they’ll go to a strip club and that the fiancés brother is attending so things won’t likely get out of hand, but I would love it if someone could say, just let him be a good friend and understand he is doing what the group is doing and don’t be spiteful or mad at him 😂😂😂 because I feel the anger slowly creeping on....
