My fiancé and I were having dinner with our friends.  We were sitting beside each other having a normal conversation.  This bitch walks up to me and tells me to scoot away, and that she has a crush on my fiancé and it's upsetting her that I'm sitting beside him.  She knows we're together.   I was pissed off, I just said he's my fiancé, if I wanna sit beside him I will.  She then tried to sit between us.  I didn't know how to even react... we just ended up leaving.  What would you do?
