So evidently your girlfriend was bisexual, had you always known that? It makes me wonder if that was the reason she wanted to open the relationship. Yet it doesn’t sound like you are bisexual, so opening it up was slightly different for you perhaps?
Yes, it was absolutely horrible.
And yes, very interesting that you bring that up. My girlfriend was bisexual and had just told me about it a few weeks prior to the open relationship conversation. Before that, I had always just assumed she was a lesbian like me. I think her suggesting the open relationship (I think you may be right that she’s the one who suggested it) might have been about exploring her sexuality a bit more. Nothing wrong with that, I just wish I would’ve been given all of the facts.
Thanks for reading!
