<human>: Ok, long story short... On and off with this girl who treated me terrible for a good year.  We hooked up again and then a few days later called it off because she went and was hooking up with others.  Whatever, wasn't dramatic about it, just said "ok" and that was that.  We were still friendly but I kept contact limited.

This was weeks ago.  Out of the blue, I saw a few days ago she completely deleted me on all social media: twitter, facebook, etc.  I'm trying not to care since I was trying to go cold turkey, but it does bother me a little bit if I'm being completely honest.  I don't know why.  How do I not let it get to me, what would be the point of her doing this?

Could you distill the essence of the text into 1-3 sentences?
<bot>: On and off girl, we were on ok terms even though she treated me like shit, she nuked me from everything out of the blue.  How do I not let this affect me?
