My FI and I are wanting to do a combined bachelor/bachelorette party. The problem is that my mother is assuming that she is invited already; his mom too. We haven't even decided who of our friends are invited or what we will be doing. So I don't really know if we want them to be there/if that would be weird for them to be there. I am wanting to know if anyone else has had any problems that are similar or if they have had their mother/FMIL at these parties and how that went. TIA.
