My fiance' called off the wedding 1 month before it was to happen and moved out of my house. She now is dating my best friend 3 weeks later. They both say they leaned on each other with her going through a broken engagement and him (my friend) going through one as well. It seems pretty suspect that he called his engagement off and my fiance and him started talking a lot and then boom she tells me she doesn't love me anymore and has been unhappy for a while and calls our engagement off. So my question is are they just trying to replace what they lost with each other or was she really not in love with me for a while and just saw he was avaiable now and left me for him?
