When she left you, she removed herself from certain advantages of being M to you. Would you agree? Do you believe you should still provide and protect, although she claims she doesn't want it?
You are a nice-guy who is telling himself he would be doing this for his kids. You want to be a good role model. What exactly are you teaching them? That a woman can disrespect her H, be unfaithful, walk out on the M........and he is suppose to cater to her needs?
Truthfully, much of this are you really afraid of looking like a jerk if you don't give her the car? Only now........you are feeling that maybe you should sell it in order to provide her with the means of getting her a car.
How much of this did she consider when she chose to leave you? Where so you draw the line of protecting and providing?
You know how I can always tell when a man is a nice-guy? B/c he always tries to find an excuse for doing it. And if he can't find one that he thinks will justify, then he will fall back on doing it for the kids.
I am probably the only woman on the board who would see you in any way other than being a wonderful father to his children b/c you went without your car in order for your WW to have it. Maybe it's b/c I see through the nice-guyness? Maybe b/c I know she has to experience the tough side of reality before she begins to really change her mindset? Whatever, I don't think this will get you closer to reconciliation. And if you come back with another excuse..........your nice-guyness will be shining brighter.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
