Opinions please: She wants to make my wedding her coming out party

[HIJKLM]

DF's half sister just began her first lesbian relationship about a week ago. She texted DF today to ask of she could bring a guest to our wedding. DF said "sure, who's the new fling?" her reply "well let's just say it's between two ladies." they text back and forth, he asks if her parents know. DF's father and his wife are devout mormons, this isn't gonna go over well... She says "nope but they'll find out at the wedding though lol"

Here's my thing... I don't care if she is a lesbian but my wedding day is not the time to tell her parents who are not going to take it well. Any other day I'd stand up to her parents and have her back but not on my wedding day...

I say she needs to come out before the wedding or not bring her GF. DF says its their business and we should stay out of it. I foresee drama...

WWYD? Tell her to come out before or not bring the GF OR just let it play out because it's their business?

That needs to be done prior to or preferably after the wedding.  Your wedding is not the place to do that.

I would tell her no girlfriend or she can stay the hell home.

She sounds selfish and a drama queen.

If she wants to bring her GF and she is allowed a guest then who cares. The only way the drama would escalate is if those not in the know made a big deal about it. If they do it's on them, not her and her s/o.

Personally I wouldn't want to bring someone to a family weeding I had only been with for a very short time, but that's just me.

Yeah, if It was me i'd just put my foot down, even if it makes her or your DH upset. This is YOUR day (well and your DH's but you know what I mean), you want to create amazing memories, enjoy it, have a blast, not having her mess everything by coming out even more so if their parents are so religious you KNOW it won't go well.
I'd go as far as to keep her from coming, even not letting her in if she still wants to go through with it.

Quoting HIJKLM:

Exactly... This will be the first time I've seen all of my family in at least 3 years. I want to enjoy it not be in the middle of a ton of drama.

Quoting SB2217:

I agree with you. I would just tell DH to tell her that, either she comes out before, don't bring the GF or just don't come, but come to your wedding to cause drama and take the focus away from a happy celebration is just wrong.

I know right? DF is so non confrontational. I just wanna kick him in the shin right now!

Quoting karla85:

How can you stay out if it if she is bringing her gf to YOUR wedding?

[LoriLou75]

I agree with you. You need to talk to her about it.

Do people really say "this is my half sister/brother" all the time?

Why is the "half" such a big deal?  Why aren't they just sister & brother?  Does only sharing part DNA make them less of siblings, they care about each other less?

So glad my children don't feel this way, my kids never say half thankfully.

Anyway, I would tell her if she brings her to keep it as friends & to please not ruin your day.

It isn't an appropriate day to come out.

It's not your business??? It is your wedding!

[Anonymous]

No, that's rude of her. She needs to tell her family beforehand or not bring her date to your wedding. It's your day, not hers.

[BekahBrownEyes]

Okay...lol...I had not read some of the replies. Since she's just a immature drama queen, I'd tell her no freaking way.
