After I left my ex-P I contacted a few friends I share a hobby with to let them know why I'm not around anymore. I had to move out of the area, so will no longer see them. One of them is male and in his late 60s, we would often have chats about common interests. He has been emailing me to ask how I am since the split (quite traumatic) but I'm not very happy with the undertone of his emails. They have become a bit over familar and gushy towards me. I'd updated him on my impending move (don't worry I haven't given an address) and to let him know I was doing ok. His last email worried me as he said "I'm signing off now, but could talk to you all night". I feel a bit creeped out by it: a) he could be my bloody father as he's in that age bracket. I'm really not into older men at all and b) he is married!
I don't want to be nasty, but I want to gently say 'back off' please. Any ideas or shall I just keep any further emails far and few between with simple updates? WWYD? I really could do without this!
