When you have this insecuity means you my have a doubt about him also, i know exactly the way you feel i was beeing going through somehting similar too and my feeling that he is still with one of his ex finaly come out. My advice to you is not get jealouse but talk to him and if you see he is nervose and trying to evoite this you can be sure he hide something. But if he told you that she call and he is open to you... then is not his fault that his ex she still look for him and he want to be with you not with her. Hope this help
Some we don't have luck to find the true one, the one who is able to love without fear and the one who is able to make you laugh each day and night, the one your not living in fear with.., the one that knows to respect you as woman and also as friend and lover, the one that smile when your say a stupid thing like : I know how you can touch a star!, are less and less those men is hard to find the one who complete you.
I am a dreamer and i deserv a men who can make me dream and laugh if i can not have him i rather be alone.
Maybe she call you back cos she feel sad and she misses you as a friend not necesarly as her bf. Remember girls when they broke up of somebody they are very sad and need to talk about it.
I hope you do your surgery and you recover fast, can't wait to hear how it was.
RE: Feeling Lost
Stop complain and do something about it. STOP FEELING SORRY FOR YOURSELF.
