Posting for traffic as I am fully aware that I am being absolutely unreasonable.
I am 40 years old, married, have around 5 very close friends, whom I see separately.
One of these friends, I have known since school. We have always kept regular contact, although much of her twenties/thirties was spent travelling, so her visits home would be sporadic and sometimes last-minute.
My issue is, I am irrationally jealous of her having other close friends, even though I have other close friends! She recently reached out to someone else she was friends with at school, who she hasn't seen for around 10 years, and I felt a childish jealously of 'what if she finds her more fun/prefers her to me and I get pushed out?''. She even invited me out with them, so it's not like she's not trying to include me.
Does anyone else feel anything like this? I wonder if, because I've known her since teenage times, she can evoke these teenage feelings?
