From hooking up with her to falling in love with her, she knew she had a girlfriend but didn't let her go. She just couldn't understand what she wanted.
She went from looking for comfort from others after being broken up to turning into a "scumbag". She knew she couldn't do anything but did it because she just didn't want anyone to get hurt.
