Bridesmaids

I'm in a similar boat. Does your FH have any female family or friends. My bridal party is my BFF his sister, and either one of his sister in laws or his oldest niece as a junior bridesmaid. Barring that it doesn't have to be even if you don't want it to or you could go non traditional and have a male friend be your bridesmaid (bridesman?) I considered that too.

I considered asking my male cousin (cause my only male friend is the officiant) but he's getting ready for his own wedding so he doesn't have time sadly. My FH's family is pretty slim like mine, his cousin said she might be my BM but she doesn't actually want anything to do with the wedding so we haven't really spoken since the day I met her.

You choose who you want (your nearest and dearest) and he chooses who he wants. There's no need to struggle to pick people you aren't close to just to meet some arbitrary number. You will both be happier if you each pick those you are closest to and leave it at that.

I think it'll be fine if you just have your MOH.

I've seen a lot of wedding where the Best Man is already standing at the altar with the groom so his 2 GM can walk down that aisle on either side of your MOH and it'll look cute!

For pictures, you could always have your officiant (because you mentioned he was your close friend) stand in as a bridesman if you're worried about the pictures not looking more even.

I agree with the PP. I'd rather have people up there that I'm close with and not "fillers" (not being rude just couldn't think of a better word lol).

Your numbers definitely don't need to be even. You pick who you are close to and if they don't match, it's totally fine! You don't want people up there standing next to you that don't mean as much to you just because you think you need to meet a certain number!
