Me (F) and my gf have been together for some time now and our relationship (if very slowly progressing) is pretty solid. However I haven’t told anyone I’m a relationship or that I’m gay. Onto the issue my brother recently confessed to me that he thinks he’s attracted to men and woman alike. And now I’m conflicted if I should break it off with my gf because of that. Like, I want my parents to have at least one normal child who isn’t gay? We’re (even tho mostly accepting) pretty conservative in our values and views sooo…. Would it be valid to break it off with my gf because of that? Like do Yall think she’d understand? Because personally I value my parents literally above anyone else

In conclusion would I be the asshole if I break up with my gf?

(Sorry for grammar and spelling errors English is not my first language)

Edit: hello everyone, I genuinely didn’t expect for more than one person to see this since it’s literally my first post and all. Thank you for everyone giving me their honest opinion and trying to force sense into me. I made this post because that’s how I’m feeling at the moment I’m terribly scared to disappoint my parents and I see that it’s mostly my own homophobia towards like myself. Anyways to those saying that maybe I should still break up with my girlfriend because “she doesn’t deserves someone like me” I think you’re right. I do really really like her but I think I first gotta handle my own shit first… any ideas of how I should do that?
