Neither. I guess my problem is that I'm really quite shy whereas my wife is outgoing and bubbly. She loves parties but I often feel a bit awkward and uncomfortable. When I'm sane I love to see her having a good time with anyone, when I'm crazy (1% of the time) I just burn up inside and silently smoulder.
nicolaou,
have you told your wife how you feel?
I agree that it probably stems from insecurity...almost all cases of jealousy do.
(I was once insanely jealous, and it was the most horrible feeling in the world, but it was all because I was so very insecure and had lower than low self-esteem)
You can try to reassure yourself that she is not ignoring you...and try to mingle more yourself, despite how difficult it feels,
(I know, I am an introvert, so I know this is NOT easy)
but, the more you do it, the more confidence you build up in yourself, and the better you will feel about your wife's having fun, since you are now having fun too. I know that sounds simplistic...but sometimes, that's all that is needed...just a self-esteem boost.
The easiest conversation is one where you are taking an interest in the other person, (without interrogating them lol), and they will in turn, ask you questions about yourself...and then you have a conversation...that's what helped me get over my nervousness of talking to people, asking them about their jobs, families, children, hobbies, (without being nosy).....maybe you have a better idea? just go with whatever works for you!
