Bro, no point in trying to figure out what she's doing. What you need to figure out is what you're gonna do. In some of your other posts, you definitely still seem preoccupied by your past relationship (totally understandable). But you need to make it up in your mind whether you're still on the hook as her safety net.
When she comes at you rational, sweet, seductive, telling you all the things you want to hear; when she gets you out in person and give you that look (you know the one), are you going to be able to do what's best for you?  :)o you know what that is yet?
Her safety net? No. F*** that.
I already know what I need to do; I'm getting to know someone healthy very slowly.
The way I see it is, I can sit around and play games in my head about her or I can simply be present and take what life is offering me now. I just sometimes wish that I would get the right opportunity to tell my ex to f*** off back to hell.
