She is not even think about you. All the decisions are coming from her. When she want she start talking with you and stop talking with you.
Has she ever care about your emotions and feelings of heart? A girl who went physically twice in past and still want to maintain friendship with them looks very odd.
Your entire problem which you stated above clearly says that you have lost your identity. You have to think about your self-respect. Kick her out from your life.
Thanks for the advise, She is like a wave where when her friends are around or when her life is all busy and happening she forgets me, but when she gets lonely she starts to initiated a conversation and try patching up. I am very sure in few months before I leave abroad she will definitely try another drama to hold me back.
I am just not sure how to approach that moment and how to react.
Any expert suggestions is really appreciated………………
