OK, so she's a slightly difficult girl sometimes - who isn't? But I have no idea why this has happened. She can be sensitive, but I don't recall doing anything specific. Obviously I have.
I'm not sure when it happened either; I remember seeing her status when it was voting, so beginning of May. But I noticed last week that she had unfriended me. Nice. I had seen her the previous weekend at DH's birthday party, but I was rushing around sorting food and stuff and didn't have any long chat; she's not the most chatty anyway.
What do I do? Unfriend the other SIL? [*They're in a civil partnership, hence 2 SILs! SIL1 is DH's sister, SIL2 is her OH; SIL2 is the one who has unfriended me. Sorry, that got a bit confusing!]
