One of my closest friends is a man, both single, always fairly clear boundaries around it being platonic only. We've long been in the habit of telling each other a lot about our lives, hopes, insecurities etc as well as our day to day lives. For example last week he both told me what he had for breakfast, what he did every evening, what he's watching on TV and what he talked to his psychiatrist about- to give you a feel for the range of topics. He encourages similar disclosures from me too, always asking what I'm up to, how I'm feeling etc. It's more intensity than I have with anyone else.
He's started seeing someone - it's early days, but he really likes her. I think it's great, but don't want to confide in him as much/talk to him so much anymore as feel weird relying so much on another woman's man. I also know how it would look to her, and if they do get serious know it's just a matter of time before things change anyway. I guess I'm protecting myself too. Also last time he was involved with someone he ended up telling me so much about her it made me uncomfortable when I met her.
I've found myself pulling back/not replying to his messages as much and know it's just a matter of time before he asks what's wrong. AIBU to do this or am I being silly? And if he does ask WIBU to tell him?
