My GF broke up with me quickly. She said she loved me a lot previously. Now says she's not " in love" and dropped me quickly. Separated everything and now is so cold. My friends think she might be bipolar.
Girls have coping mechanisms that allow them to stay in a relationship all the way up to the point they want out. Are you saying she has mental problems because she broke up with your or were there other things as well?
Because it's always possible she just stopped liking you... Most relationships do not succeed... Hence "dating."
