Its either that I really don't understand girls, or I'm in for a heartbreak.
Unfortunately from personal experience, get out while you can. I know that's the easy option that most don't want to hear but this girl seems to be putting a lot interest into this ex if she really wants to just be friends with him then she wouldn't be hung up on him. No two relationships are going to be alike. Now there's a history between them. Just ask yourself is she really worth it? If she is then find a way.
