am I being too controlling?

My husband begged me to have a coed baby shower. I hate most of his friends as they are all not quite right and all immature. So I am nice and give in and he is nagging me for months about the party. I would have rather not even had a shower. I don't want a lot of attention on me it just is too uncomfortable. I also had to plan nearly everything myself for the shower. Now he says he's having a boys night after the shower. This is because his friend is getting married in august and his two friends are brothers and they live 1-2 hrs in opposite directions of each other. They are leaving me alone that night and going back to their hometown 45 minutes away to drink and chill. I feel like They are hijacking my day. I would like to spend time with my husband and no be left alone at eight and a half months pregnant! He is a tax accountant and works 100 hrs a week and hasn't come to any appointments and hardly even asks how I am doing. He makes good money and he feels entitled to do anything he wants without regard to my feelings.
