I don't understand why you think that woman is all what you are not....and if you think this way, then it means your husband wants a woman like you, the one that is not like the other woman....
He's married to you for so long and he wants you....why are you creating a monster for yourself?
I'm a jealous type of person and I'm working on it....good lord, god gave me a boyfriend who just has girlfriend and absolutly no guy friend....can you believe that? I think God is punishing me for being jealous...and you know what it is funny about it? my boyfriend is so sad that doesn't have any guy friend....hehehehe....
just be relax and be confident that nobody on earth would be "YOU"....you are special and what you are offering to your husband, nobody else can replace it....you guys have history together....and that's count....so be relax....and take care of yourself....
also, stop checking the other woman's profile...who cares about her? wish her a best luck in her life too....
