I'll start off by saying that my fiance was married before. The marriage didn't last very long and I have never been married. Previously, my fiance's ex had a bachelorette party which included his brother's wife as she was in the bridal party. His mother was not invited to the BP, but was hurt upon learning that the bride's mother and aunt were invited and attended. Fast forward to me. My two sisters are my MOH and my fiance's sister in law is included in the bridal party, but will likely not attend a BP because she will have had a baby 4 weeks before. My future MIL was hinting at coming to the BP, even though I wasn't planning on my mom attending. I really love my MIL and want to make sure she's included in things, but this feels weird to me. The BP is likely going to be my friends and sisters, I honestly don't think anyone from his side is going to attend. Help
