First- Hi everyone! I am new to this sub! 

 Let's give you some background about my situation:
I have been...dealing with my long-distance uBPD girlfriend for one year and a month. As you can guess, we've been on and off a lot. However, in the last three months or so, I thought she was really changing for better as she'd gone too far and I was so mad that I had her blocked for two weeks and during that time, I learned how to have my act together, especially with her. Now, here comes the reason for this post- four days ago, as we were texting, she sent me a photo of something, I don't remember what because my messages are set to auto-delete after 24 hours, but it was something in her room which was concealed by a ''Paint'' brush, and said: ''You are not gonna see it hehe'', and I replied ''Ehh you are awful! :D''. Here's how the rest of our conversation went:
Her- I am awful?
Me- Yes, you won't let me see it, how dare you? :*
Her- Literally everyone has it in their own room
Me- I was joking
Her- But I wasn't. I am awful after all, am I not?
Me- Oh, God...
Her- I can't believe you called me or would ever call me ''awful''
Me- Listen, you know pretty good what I meant by this because that was the most innocent joke possible. I am done with walking on eggshells. If you find something wrong in my joke, it's you, not me.
*Two hours later......
Her- Yeah, I overreacted.
Me- As always
Her- It's not always
Me- Fair enough. As expected*
Her- I admitted to overreacting. There's nothing else I can do for you.
(Also her) Besides, if this is bothering you, you can always find someone who doesn't overreact ''as always/as expected''.
Me- Oookay...
Her- It's always a problem when I don't like something but never when you don't!
Me- Alright, I got it.
Neither she has reached out since, nor have I.
