I need your help.. please help me with this.?

You didn't say how long you dated I suspect for awhile. Anywho she must feel comfortable talking to you. She needs to know you'll be there to talk, she's not considering how you feel. Tell her Hey I thought when we broke up we could be friends but I was wrong. Tell her to give you time, then maybe friendship will happen. You do and will move on, this wont be your last love.
