sounds like you have been with your GF through thick and thin, if its going on for three years. Can't you be confident in her after such a long time together? I have BPD, and my BF left me after 2 years, not wanting to deal with it, but I never ever ever thought of cheating on him. And this has never ever been an issue with us, although, like you and your girl, we were fighting over nothing so many times. See, all people are different and usually people develop BPD rather early, so it doesn't mean that if she was faithful before - after being diagnosed, she will go far and wide changing partners, no no, this does not happen like this. I am really glad though that you are dealing with her problem and are still with her.

umm yea...u kan say that...i would think i could trust her by now but its complicated....uc within the last few months weve been fighting more and more....she claims to be asleep for like 12 to 13 hours a day....when she always used to sleep about 8....whenever we dont fite even still shell wake up after 8...but everytime we fite she "sleeps" way longer than usual.i feel either shes seeing someone at night or in the morning..most likely during the night...she claims to turn her phone off...i dont know....i really wish things could be different....if she would just see how faithful i am and i have been....im really feeling like i cant take anymore of this....
