My best friend lives in Australia. Whilst he was working here he became part of the family, came to ours for Christmas, was ferried all over the country etc. In fact when DH and I met he sometimes came on our dates so that he wasn't left out! I thought we were really close. A mutual friend tonight put on her FB that she had just picked him up from the airport. About an hour later he messaged me asking if I was around tomorrow as he'd like to pop in. I was really upset. It felt as if he'd only asked to see me because he knew I would see FB. I asked him if that was the case and the mutual friend sent a message saying I had upset him. I am currently struggling with severe depression and realise I can get things out of proportion atm but I'm gutted. I can't stop crying. Do I need a slap?
