I think my ex had a bit of date fetish. 13th of march, on that day we set the facebook relationship status (she did, I didn't mind). Recently I found out that on the exact same day she broke up with her boyfriend and kicked him out of her life. He had no idea about me until he saw me on her facebook profile and I had no idea about him (she had told me she wasn't with anybody for 6 months), I was a classic replacement. Interesting thing, 13th march was their anniversary date, they dated for 2 years. On the 13th of March two years before that she did the exact same thing with the boyfriend before, the 2 guys actually had a fight over her that day. I didn't manage to stay in the relationship whole year so I have no idea how she 'celebrated' this years march.

Anyway, I wondered maybe the triggering dates can be some important childhood events, something to do with the parents. I have no idea but there have been a lot of people noticing that some dates really matter for BPDs.
