Change your religion for her man, chase after her dont let her go over a petty thing like that. But then again deep down you truely know how you feel. If you knew you wanted her for the rest of your life deep down you would have done anything to get her back, no excuses. Or a part of you feels you will move on. It does hurt, i feel i have been on the female end of this i acted as though i was in love and happy but didnt really know what love amd happy truely meant like he did. I essentially led him on and when the honey moon phase passed i moved on and he didnt understand what happened. It sounds like she didnt love you as deeply as you loved her. I think down the road you will find someone else you love even more that loves you even more back amd youll think back to this relationship amd think that love was silly.
