I recommend getting out of the relationship, unless you really like her and you have to be assertive about that, and if her friend tries to get in the way, push her out of the way. I've had experience with a bi girl, and unless you do everything right or are assertive, you won't get her.
I honestly recommend leaving, but it's up to you.
>>6I agree with Robo, actually put something down worthy of anybody to actually read. Fkin' cunt.
