Ahhh she's a double water sign... that might explain it... I don't really put too much emphasis on astrology.. but she might be so emotionally attached to him that its tough for her to see the situation clearly.
@nataliaaa I'm really not bitter, its not my life. I just don't want to see you driving off a cliff if I see you on your way to doing it. If anything I am angry that the guy put you in the situation to make you test your own fortitude, He should know he's wrong.
A man that loves you wouldn't jeopardize you over her. one thing he could have done is let her use his place and stay with you or something.
