What can I do to save my marriage? Help

[Sleepy]

Ok, I've decided to take the tough love approach and be a man.

This morning she discussed the days plan for the kids. I am on vacation and the kids are off too (soccer camps and Dr. visits). She was going to work. She talked down to me like a child and I made some sarcastic remark about her giving up on the work uniform that she wasn't wearing, which she retorted back "see... you are so mean to me, you will never change"...... It's always my fault.

Later she calls me and says she forgot her cell phone in a real nice sweet voice. I suppose she wants me to bring it to her. I can see through that manipulation.

Tonight I take back my bedroom. She can stay or move out... the choice is hers.
