DP has female friend - ex-work colleague - who lives in Australia. I think there was a kind of 'might have but didn't' get together thing many years back.
When we first got together (9 years ago) I did say something about the fact that she was always the first person to wish him 'happy birthday' or 'happy xmas' which was a bit unfair but that was early days and he must have said something as she no longer contacts him via phone.
What she does do is email him (no exaggeration) about 5 times a day to which he replies. I don't read his emails but his laptop is always on and I can see her name in the list of emails and a long line of re: re: re: etc for ages.
He says this is all inane chitchat about what she's doing, who she's seeing, what music/tv/progs/films etc she's listened to/seen. But this is every day. Including weekends.
My point is that to be so involved in the daily stuff of someone's life is rather intimate and you don't engage in it unless you are getting something from it. He won't tell me what that is nor deny it, but insists she sees him in a father figure role (she is 20 years or so younger).
I just think it's inappropriate. It's not about me feeling insecure but if I was having an ongoing email exchange with someone I know it would be because I had strong feelings for them and wanted to feel close.
AIBU?
