stories - Friend - rival

I am 38 y. old and happilymarried for many years. We have two
wonderful children. I have a problem that many wiveshave, so I would
like to help me with advice.
My husband has a childhood friend who married 3-4 years after usto a
woman I can briefly describe as the dream woman for every man -
pretty, with nice body, kind, helpful, etc. I also liked her we are
family friends for many years.
My husband is not the type womanizer, and keeps family and family
values close to his heart and with few exceptions we haven't had
problemswith the opposite sex, but I was consumed by a secret
jealousy, which sometimes makes me behave abnormally and that bothers
me.
We visit our friends on many occasions and often I feel like a
"secondhand" woman not because my husband offends me or something,but
I see him take sleek looks at her and feel his adrenaline, which
increases when he comesclose to her/ no way all men feel that way /,
but this is the same looks andpassion with which he looked at my
before and although I have tried to keep good appearance, be the
perfect housewife,mother and mistress I have a feeling of helplessness
because I know that even if nothing happens he's in love with her and
fight with himself internally.
Please advise me how to behave – don't want to ruin the relationship
with our friends, it makesme feel like the villain of the story the
more because they are friends of the children, but at thesame time I'm
afraid of the events that may occurand destroy the harmonyin my
family.
