Wife said she was done!

[movingon-1968]

I have to accept the only thing I can do is to continue to improve on myself and not to allow her to get the best of me.

It's not easy, but, that really is the only approach.

She was angry last night and when she discovered I was not going to engage with an argument she requested we drop the house price by 10%! I never validated this. Should I? I strongly disagree because its a big chunk of change.

I wouldn't engage in an argument over it. But, you could give her a chance to state her reasons why she feels it's a good move (I do not know from your post if you did), as that would at least give the appearance that you care about her opinion. If you just didn't respond or ignored her that's not conducive to progress at all.

Afterwords she went on the computer (open screen in the living room)and proceeded to chat with 2 guys and kept looking back to see if I was noticing. I never showed any reaction and continued to play with our son. Feels like she is going out of her way to hurt me. If i am writing about it I guess it did bother me but I never let her see that it did.

It does seem like she was trying to make you jealous, but, that's really just mind reading. It's best to not acknowledge it and carry on with what you are doing - and do it happily. You have to convince her you're ready to move on. But you need to be prepared for that yourself...
