I will start with some context/background.
From 18-22 I dated a guy, he was my first love and I imagined I'd spend the rest of my life with him, however the relationship started to breakdown and we split, it was very much mutual.
About a year latter we became friends have remained so ever since, I've met several of his girlfriends since and he was at my wedding, knows my children etc.
It has been 11 years since we broke up now.
Recently he came over to watch a sporting final we both like and he told me about this girl he is seeing, he asked me to meet her as I have good judgement - no problem, we have done this before and are just good friends now.
Here is the issue - I'm ridiculously jealous of her, she is exactly the type he has been looking for and he is ridiculously smitten! I have no idea why it is having such an impact on me when I'm happily married with 2 kids.
She is younger - mid-twenties, works for a fashion magazine, absolutely stunning, effortlessly cool, well travelled, very smart, a little edgy.
As a person she is quite intimidating to me, very fashionable and cultured people always make me feel a little inferior. Added to that intelligence, stunning looks, athleticism and everything else it makes me feel tiny.
Worse than that, I have never seen my friend want anyone this bad - not even me in the early days. All he talks about is how great she is and how much he adores her and how his family (French) will love that she is bilingual and extremely smart. His parents detested me, so that just stings a little.
I know that jealousy is a horrible emotion but I don't know how to shake it, I don't think I've seen him love anyone this much ever!
AIBU to feel this way? How do I get over this before it impacts my marriage?
