Namechanged for this, but regular reader/poster, honest!
My cousin and I are very close - she's 18 months younger than me, but we grew up together and are more like sisters than cousins.
We're now both in our late 30s, but she's much more 'exciting' than I am - very well-educated (PhD level), international career with lots of travel, lovely, high-earning OH, beautiful house, no kids.
Also, she has a lot of time to spend on herself: she's very fit, spends a lot of time in the gym/doing sports and is very naturally beautiful anyway (she was the baby when we were growing up and was very petted because of how 'cute' she was).
TBH, I was always a bit jealous of her when we were little, although we've talked about it and laughed, because she says she envied me!
As I say, we have a great relationship and she is a terrific person, but I feel really envious of her: my DH LOVES her and is always talking about her, especially how about how well turned-out/fit she is.
Again, she is a lovely person, loves me and my family to bits and her own DP, who she's been with for years. I've got no reason to think she'd ever do anything to hurt me.
She and her DP have just left after staying with us for a few days over Christmas and now DH and DCs are banging on about how fabulous she is.
AIBU to feel a bit resentful? Also, does DH fancy her?
