Yesterday, was the first day where I completely felt over my exBPD. Today was similar. Until I got a hair cut after work. Had a few errands to run after that and was being checked out constantly as well as had two girls go out of their way to flirt with me (rather attractive guy and with a fresh hair cut I turn heads). For some reason this seemed to trigger a bout of depression, missing her like I haven't missed her in months, and my current insomnia.
Your healing and forward progress isn't going to be a linear clime, one step forward after the next. Fits and starts like that one are to be expected. Have you recovered any from it in the next couple days?
Be patient with yourself.
There is another girl who I have been interested in for a while, but don't want to mess her up... .She doesn't drink, doesn't do anything risky, and has never had sex (despite being very attractive). I know without a doubt I'd be bad for her in my current state and not something I'd ever want to do.
I'm not quite sure what you mean here, but this bit about messing her up in your current state has me wondering what you mean too.
I'm a little confused here too--If you were in a 11 year r/s, you have to be nearly 30, if not well past. How old is she? If she's way younger than you (say, ~20), then having never had sex seems reasonable/normal, if not common. If she's over 30, that is more of a

red flag that something is really weird about her, especially since you say she is attractive.
