You question does not indicate what her feelings toward you are.
You imply she has hurt feelings because you want to be friends.
She is too imature to understand you intentions. You are intend on having a friendly relationship with someone dealing with the pain of losing a more intimate relationship. Keep your distance from your ex until she can come to terms of the relationship ending.
DO NOT under any circumstances be intimate with her unless you want to have a child with her. NO MATTER WHAT SHE SAYS. THOSE ONE LAST TIME OFFERS.. ARE TRAPS.
If you don't give this ex time to heal you are not being a friend. Some times being a true friend is letting go. Stay away from her - you are only confusing her heart and her mind. Which is why she cant believe your over her. Stop any initalizing contact with her and prolong any return calls no luches.. dinners.. etc.
You should give her space.. otherwise your going to be a Daddy paying child support - or in a marriage that never should have been. Or worse yet.. end up on the evening news... because if she cant have you no one can. Vee
