its sad to hear that. I hope things will be alright for both of you. But can i ask the same thing as others have asked, is she like that before? did she contacted you now since she went back here? try to check also if you did something wrong to her...if you think you did what best fro your relationship and she still likes that, time to think

remember that marriage work both ways, both of you must love each other. it cant be a oneway relationship. you must realise that loving someone who doesnt love you is just like killing yourself. if you think its only you who loves her, better end it as early as now...while the pain is not that deep yet
