WIBU to not invite homophobic dad to my wedding?

[Appril]

I've been in same sex relationship for 7 years now and my dad has never accepted this. I was really close to my dad as a child but we drifted apart when my parents divorced and he moved hours away. I never told him I was bisexual, I didn't feel there was much need to, I'd never really told him much about my previous relationships, I just didn't tell him those sorts of things. However about a year and a half into my relation with my DP i decided to tell him. I knew exactly what his reaction would be like, he said something along the lines of "since when were you a lesbian?" And told me I was making a terrible decision, the same thing he told me when we got engaged. He can't seem to accept that we're in a serious relationship, he introduced her as my "friend" to his girlfriend's family once. Now there's our wedding and I can't decide whether I want him there or not, besides from this we haven't had any significant problems between us, although I'm not particularly close to him. But this is a big part of my life. I want him there as he's my dad but at the same time I don't. I know of course this is my decision but I was wondering if anyone had some advice

Have you talked to him since you he said you are making a mistake? If you have, has he apologised?

Go from there as you know in your heart of hearts whether to invite him.

Remember weddings are a day, marriage is (hopefully) a life time.

If any of my parents were even remotely embarrassed or disapproving of my relationship or the fact that i’m bi then i’d be no contact.

Do you really want to invite someone to your wedding who will potentially be slagging it off all day?

It's been an on going thing for years that he's never apologised for, no matter how much I try to explain he doesn't seem to "get" why I would love a woman.

I’d probably be honest with him and say, dad I would like you there but obviously if you’re not supportive of my marriage then it’s not going to be possible and see what he says? Then you’re making the decision his. Either he then supports you or he doesn’t. But you will know you did what you could.

Agree with Asta.
Is he likely to say anything in the day to embarrass you or your partner?
I’m thinking maybe approch this as a possible turning point, Dad I know you haven’t understood in the past, I’m in love and happy. I understand if you don’t want to come to my wedding. Let him choose so to speak. It may be an excellent time to reassess, I’m not condoning his awful behavior at all, however a generation ago attitudes were very different.
Congratulations to you and your partner.

Hilarious that he thinks you are making a mistake. Like you get to choose to be attracted to men or women 🤦‍♀️
Sit down and have a talk to him
“If you support my choice and are happy for me to marry my dp then I would like you to walk me down the aisle/be a part of our wedding. If you don’t support our union then there is t any point in you attending.”

Personally - for me it would be a No. I have personal experience of this but I do think previous poster’s suggesting a final attempt at “I am happy, and I want you to share the day with me” could be a good call?

I would have said you should give him another chance as he may have changed his mind over the years. However if he said that your engagement was a terrible mistake I think that there is no return. His negativity about your marriage could spoil your day so I wouldn't invite him.

I also agree with Asta.

Essentially him behaving this way about your relationship is invalidating your fiancee and that isn't okay. How does she feel about it? Her feelings should come first here, not his.

Thank you for the suggestions, I think i will feel better talking to him first rather not just not inviting him at all, DP has said it's up to me to decide
