ive been dating this girl for over a year. our relationship started off great, but randomly last year she ended things. as days went on she would always try and keep me around but would never date. then she started dating a new guy, but would always call me for sex. she always said she does not want me now, but will later on. after a few months she broke up with him and came running back. she has been trying to date me, i have caught her lying about many things and all having to do with this other guy. she has gone to see him and other things of this sort. now she says she feels bad and is sorry and clames she has changed. can i trust her, is their hope for a trusting relationsip?
