Why is my ex telling me all about her current problems?

So I was dating this girl for about six months. She is a lot younger than me- 18. I am 25. I broke up with her before she left for college and she to get over me and started a new relationship. Then over Christmas break we rekindled our romance, only to have my heart broken this time. She told me that she wanted to be with me and that she would break it off with him. However this did not happen she eventually chose him, after we tried to just date on the side for a while. Being a little older I realized this would not work so I suggested that we be just friends. This was about 3 weeks ago. it has been going ok, except she has been being quite shady. Until yesterday when she found out some things about her current boyfriend that are making there relationship hard. He does not love her as much as she does him. All of the sudden she has felt the need to call me crying and tell me every detail about whats going on with them, also she has been texting me all day with messages of no importance, meaning small talk. My question is why all of the sudden is she talking to me more and why does she feel the need to tell me details about her relationship? I mean I know we are friends but I don't see myself as that type of friend as she knows I still love her. Anyway it just boggles my mind that I would be the first person she calls with her details on her current relationship. Is she trying to torment me? Or is she trying to have a backup in case her current relationship fails? or is she just reaching out to me because she know I care so much for her? well I'm stumped any advice would be helpful. thanks

I personally think she is using you as a back up, which is horrible on her part. You should let her know that you both need to move on and that you are your own person and deserve to be treated better as a friend. If she can't respect this, then she's not worth staying in contact with.

She could still have feelings for you, she could just know that you'll listen, you need to ask her these things. She'll be the best to answer them for you.

oh you are def her back up and you deserve better!! sounds like this girl loves the attention of 2 guys wanting her and has played on that for to long! Now that she has realised this guy may not love her as much, she nos you will so now she is trying to get you back by telling you the details so you dont treat her the same, and maybe hoping you'll say something along the lines of "I love you and id never treat you that way" and then she goes back out with you! dont let her use you becos she is unhappy, she has used you for way to long!

Or is she trying to have a backup in case her current relationship fails? B I and G O. good luck Gino
