I think that I could go on for a page and a half, but I will keep it as short and as sweet as possible.
You say you are devoted to your wife, and that you are stable.
If you were, you would not make your wife feel belittled and insecure (what you call jealousy).
She knows women and how they think, and mister newlylookin (says it all right here), she has them pegged spot on.
Your attention should be spent on your wife, not other women. It's called infidelity and it isn't always physical.
You are her white knight, and if women are hitting on you, regardless of their age, it's because you are giving off signals telling them that you are receptive to their overtures.
You have a very wise and honest woman, someone rare, these days, and she seems to be trying to communicate a very important message to which you seem oblivious.
I'm surprised that she is still with you, you are so disrespectful of and to her, and of women in general, I might add.
I'd like to see how you would feel and react if the tables were turned and she was the one seeking and getting attention, support, and understanding from another man?
