I’m glad that many people responded to your post! I read it early this morning and became very angry. I wanted to tell you that you don’t need to cast your pearl before swine. The love that you are giving this woman is better spent on someone else. Even if this the relationship with the new guy doesn’t work out for her, I would argue strongly against you running back. She seems like she wants to have her cake and eat it too. Don’t give her the luxury of having a “fallback” guy, unless you REALLY want to be “that” kind of guy.
I suggest that you follow the advice of others and begin to erect some mental barriers around your heart as it pertains to this woman. Get busy! Start dating! Find happiness outside of her! She is not the only fish in the sea. Sometimes being too into a person/relationship can cloud our vision and dull our senses. I have the feeling that you’ve already come to some conclusions. While you wait in limbo for this person with your heart completely overwhelmed, you may be missing the love of your life who is standing right before you.
