You seem to be commitment-phobic. I've had this problem. You have an honesty problem, but if I call you a jerk for treating your W the way you do your defenses go up.
Making sure your W feels secure that you find her attractive isn't romantic, it's a necessity if you want your M to work. I learned that the hard way.
Your W may seem a lot more attractive if you haven't seen her face for 2 or 3 mos.
