I have read that a major part of BPD can be perceived slights, both real and imagined. This can lead to "BPD Rage". I have found after accepting the demise of my relationship with my uBPDexGF that I now have 20/20 vision for the

Red Flags in the past. I can almost look back in amusement at these situations now. I will share 2 of mine, and wonder if anyone else would like to share.
A.) Early on in our relationship, we were heading towards sexy-times. I stated that I felt that there might be something really special happening between us. Immediately, eyes gloss over, I am pushed off of her and she stares at me and says "might?" I attempted to explain myself, apologize for maybe not phrasing it as well as I could. Nothing, I was shut down, wouldn't discuss the matter anymore, she rolled over and went to bed. She brings it up again early in the morning, saying that she questioned my dedication to her. I told her she was fixating on one word in that statement, while not acknowledging the general statement. I refused to talk about it anymore.
B.) I had phoned a female friend earlier in the day, to ask a question regarding LinkedIn. That evening I am snuggled up with uBPDexGF on the couch and I receive a text alert. I check it, and it says "I am busy tonight, I'll call you tomorrow to answer your questions". Again, the GF shifts into the other person. She asks "Who is Molly, and why is she going to call you" (names changed). She had seen the entire text alert, name and all. I explained who "Molly" was, that she was a friend that worked in HR. I was asked a 100 questions pertaining to this person, and every answer was matched with an air of disbelief. I even texted "Molly" back, what questions, and she responded about LinkedIn. The rest of the evening became damage control, attempting to understand where the insecurity came from and how to prove that I was not a liar or unfaithful. We goto bed exhausted, from arguing for hours. Wake up, everything is peachy keen, like nothing had ever happened.
--Side Note-- The day after this second altercation was when I found the used condoms in her trash. Possible projection from the guilt of her cheating?
