Dear Jason:
It is too bad that you are facing this problem, that is, her interest in another man. The fact that she checked out his profile in Facebook just the other day confirms her interest in him. That may have happened no matter what you did differently and it has to do with her desire for excitement, diversion, something new… I don’t believe women’s interest in men outside a marriage is different than men’s, that all women are the same- and I don’t believe she is just reacting to what you are doing wrong.

She is responsible for her participation in the relationship and you are responsible to your participation in the relationship. To what the relationship is- and to the fact that it exists- you are 50/50% responsible. Ask her (have you?) for the nature of her interest in the man, and listen. Really listen so you can figure out the nature of her interest, so that you learn what you are up against… Invite her to share honestly about her interest in him_ what is her motivation? What excites her about him… Be as calm as you can so your can HEAR what is GOING ON. Better get to know what is happening- get a better view of your reality.

After you get MORE information from her, and GET it, that is absorb it before you decide what to do with it- well, first things first. Get the information.
