Hi, this is my first post so bare with me.
I’m a 28 year old male with bpd.
Last year I became friends with a girl (29) who also has bpd. She is my FP and 90% of the time of things are great with us. When I meet her she was in a really toxic relationship with a guy who had become her FP. They’ve been separated for a few months now and I genuinely believe that she wouldn’t go back again. Since they broke up we’ve been hanging out a lot more and I started to notice that I like her so I was honest and told her. Just before she was due to go on holiday I sent her a message offering her a massage when she got back and she accepted. (Before this point I wasn’t sure if she was attracted to me to because of my dumb bpd brain) She goes on vacation and thinks continue as normal, messaging every day, being flirty. Half way through the vacation she offers to send nudes. 
At which point I start to freak out in my head, because the massage was the set plan and I’d never sent or received nudes before. So we take and exchange pictures (she deletes hers after seconds of me seeing it) and there’s a about 5 mins of sexual talk and she disappears for an hour. At which point I start to freak out (in my mind) thinking I did something wrong. She comes back after a hour and explains that she doesn’t really do things like that and she got scared. I reassure her that she didn’t do anything wrong and that she doesn’t have to do things that make her uncomfortable. It’s been about two weeks since then. We’re still hanging out  and talking a lot since she got back of holiday. She’s still flirty sometimes, but she’s said she’s fucked up and doesn’t know what she wants.
We’re going to see It Chapter 2 this weekend and will probably hang out at her place after. Do I make a move? Do I offer her a massage again? Do I give her time? Part of me thinks that if I don’t make a move then nothing will ever happen because we’ll just wait for the other one to do something. Part of me feels that if I don’t do something I will miss any chance I have.
So my fellow bpd men and women, Help!
