I think this person likes me, and I want to ask them out, but they have BPD and I’m wondering how this impacts their interactions with me and if there’s anything I should be aware of before getting into this - of course, I also intend to ask them what to expect but I wanted an objective perspective too so any words you have are greatly appreciated. 

Side note: I used to think I had BPD when it came to hardships coming up in my previous relationships but that’s since changed a little and now I don’t think I can truly know what it’s like based on my experience alone.

I really like them and hope this can work out, thanks.
