I'm newly engaged and am working some stuff out with my fiance, regarding finances and family...we're getting past some stuff, which is good, but there's one thing that REALLY is bothering me
His sister is a lesbian, who is in a committed relationship. They are both very manly, and refuse to EVER wear dresses...My family will NOT like this. They are very Catholic and old school. I was hoping they could just dress nice and act natural and no one would notice, but they refuse to hide their relationship, which I get, but it's your brother's wedding for crying out loud! Future MIL is backing them 100%, and says she will NOT attend if they are not invited. My fiance wants NO issues and feels that my family shouldn't care about what his sister does. But I know they'll have a problem with it.
I'm REALLY annoyed that his sister and her woman can't suck it up and pretend for one day...It would mean alot to us and just make things run smoothly. How do I proceed?
