(he says hes "bi" but come on thats some wanting to have your cake and eat it too bs)
Shut the fuck up
You know the guy? His history and issues? No? Then you can be the one to shut up, thanks.
Your originally quoted statement makes it sound like you are condemning the very idea of bisexuality, but your response makes it sound like you are condemning this individuals identity as bisexual. Either way it really isn't a good look for you. Feel free to call the guy a cheating POS and all that, but don't condemn the idea of bisexuality either in the cheating POS or other bisexual people.
A 100% gay guy would have never wanted to sleep with your girlfriend from a purely sexual viewpoint. I guess he could be 100% gay and want to sleep with her to cause drama and whatnot, but that'd obviously be for reasons beyond sexual.
I'm bisexual and have been dealing with this crap for a long time. Gay people think I'm straight and straight people think I'm gay. Sometimes I'll get people who just refer to me as bisexual, but that really isn't the norm. At this point, I've learned to not disclose my bisexuality to anyone until I've known them for a long time. I usually don't even disclose that type of information to people I am dating. Well not in the early stages at least.
She was never my gf, thank god
But I get where you're coming from ---
