Did she not notice you were a man when you would go into the men's room to go to the bathroom or leave the seat up at her place.

I'm pretty sure you're the only one who thought she was your girlfriend..

Everyone is assuming the OP is a straight male when they could be a butch Lesbian.

What a bitch

OP, you dodged a bullet! I bet you are young & naive, and got hypnotized by her "looks" (quotation marks since these types often spend hours getting ready, to create a look they don't wake up with) enough to not notice her lack of character. Next time pick a more down to earth gal. Maybe not so flashy at first glance, but if she's a cool person and you are on the same wavelength, the more you get to know her the hotter she'll look to you! And that's how healthy relationships happen. Fawning over some manipulative shallow bimbo who's not worth it is a common mistake for young men. No you aren't alone in feeling stupid like this. But you're only ACTUALLY stupid if you pick another one like her next time. Learn to avoid mask-wearing people and your future will be much brighter.

Don't even sweat her, the expression about a million fish in the sea is very true. It's never when you expect it btw, it can be when you're in your grubby clothing just normal grocery shopping and you can bump carts with your future wife. My point is just use this as experience of what you want in the future.

I'm confused. Anyway, I think Op is a girl who secretly fall in love with her girlfriend. Maybe, we need a vote about the gender of the Op. Lol

How did you think she was your girlfriend when she didn't know you well enough to even know your gender?
