This girl was my plate for about 10 months then we became exclusive for around 2 months

She wants to add me on facebook because she’s suspicious of me (probably because I’m not needy for her all the time)..I never brought this girl up before but I guess she saw her on my facebook friends..she’s a girl I used to fuck, an au pair that moved back to the Czech republic

We’re watching a show on tv and the Czech Republic comes up and I said seems cool out there I had a friend invite me out (she did about a month back) and she said WHAT!!?! She got all pissy because she knew it was that hot girl I had no idea she knew but I just played it off like it was someone else (I really do know someone else that works there)..we fucked but she didn’t kiss or anything, trying to take emotion out of it it seemed ...then the next day I get this

What do you think...I thought the fact she said “leave me alone” was a good thing showing she has emotion...I never smother her so the “leave me alone” thing seems like she wanted the opposite
