Re: Am I taking a really extreme step?
Ignore the women on this forum. They couldn't save anything. Firstly yes it is an extreme step. Secondly if I may, I would like to point out that you have unwillingly been whipped. From what I can tell in the posts and by my own assumptions is that you are in most cases the one to bridge the gaps and offer the solutions.
I apologise before hand for what I am to say as after this is your wife. As PCG said time to grow a pair. When a woman realises she can effectively blow you off and just be moody and you will run after her, it gives her too much control over you. I for one would just be just as stubborn as her and teach her a lesson and your wife does need to be taught a lesson. She can not act like a two year old. She has to act like an adult.
So I suggest you just ignore her. Make your own food, order take out and I would highly recommend going out for dinner. Additionally I know you spend time with the kids, but do so more often specifically infront of her. To show that you are ignoring her for her actions.
Yes this is all childish. Yes it is mean and rude. But you have to reestablish dominance in the family and in your relationship.
For now ignore the flight and ticket question. Concentrate on being man of the house again.
