Is she having her cake and eat it too? Sounds that way to me.....
Put yourself in her shoes..she is having doubts about her man....period. She would never be with you otherwise. Womean are EMOTIONAL creatures...You were giving her something she wanted from her man, yet found it in you. She is with her man because of 3 years sounds like..and she is scared to leave. Families have NOTHING to do with it... That is a lame excuse and she is digging. I would leave her be.....let her come to you YET, I wouldn't be so easy to profess my love for her..Love needs to be earned...sounds to me you are the one getting hurt...not her!
-Be Strong!
