Dump her, let her kill herself, who cares! Dont be a hostage!

That is the weirdest, most jumbled, non sequiter of a comment I've ever seen. You are such a weirdo. Have you nothing better to do that randomly insulting anonymous people for no apparent reason? How old are you?

Your a fucking prick who is now stuck with someone. You better stick it out otherwise live in regrett. Wait for her to dump you because you're a twat.

That is so fucked up. Sex is more important than someone's feelings? That is disgusting. She is depressed, shes not just some 'crazy chick'. She is a human being who suffers from a mental disorder she cannot control, and you don't deserve to have met her or have her trust you because you lack any compassion at all. Fuck you.

No worries dude, I was in the mental ward with her and fucked her every day. She said I had a bigger dick and knew how to use it better than you! Go fuck her skank bag douche of a best friend and leave Brittany to me. I like the way she screams my name when my balls are slapping against her.

call her doctor and have her commited back into the mental ward so they can give her treatment. then you can go ahead and fuck your brains out with her girlfriend.

We all have crazy ex girlfriends dude. Don't be held hostage by her insanity. Dump her and move on. She is going to do what she is going to do. You can't be responsible for that.

Tell her now that you can't deal with her drama anymore and need to move on, but don't tell her about you and her friend. That can come later. And never never let her know you two hooked up while she was in the mental ward.

She needs more help than you can give. Staying with a person for the wrong reasons will never make you happy. You can't feel obligated and feel like her life is in your hands. While I'm not saying kick her to the curb if she's this fragile, you can offer support to a friend in need and when it looks like she's well, slowly distance yourself and move on. You are in a tough spot but staying at either ends of the spectrum (staying with her vs dumping her) is no good. You sound like a half decent human being. I say half because two timing her with her BF is not exactly commendable. I'm sure if Brittany took her lifr, you would feel guilty but also know that it's not your fault. She makes her own decisions and sounds like she was already mentally unstable before you met her. Get Brittany on the road to recovery.

Well being a bitch to her won't exactly help the matter much xD

dang it, you should make her consult a doctor
