No, do not say all that whinny stuff to her. Here is what I would do,
Show up, with your stuff and simply say, "I have decided to move back in to my house with my family, for me it is the right thing to do." And then proceed to move in. Get ready for all hell to be unleashed on you. DO NOT DO THIS TOMORROW, DO IT TODAY!
The thing your wife is missing is respect for you, and since women tie their feelings of respect to the feeling of love, it is important for you to do this.
When my wife wanted me to leave, I simply said, "I am not leaving my house, I am not the one that wants to separate. If you would like to move out, I will help you get an apartment and you can see the kids anytime you would like." She said, "I do not like that at all." But, what could she do, her master plan was not going like she had thought it would. She thought I would leave, we would get the D, and then she actually thought we would sell the big house and get two smaller houses next door to each other so the kids could go back and forth. Me not moving out was the first step of getting her out of la la land.
One mistake I made was thinking a consolation for her was to move out of the marital bed into the spare bedroom. After, a few nights I came to my senses and said, "this is our bed, I do not have a problem sleeping here, you are more than welcome to sleep with me in it, if you do not want to, then the bed in the spare room is nice." She through a fit, but she did not leave the bed.
You have a man in YOUR house at night, with your wife, and you children and you do not want to mess anything up? My God, what is this teaching your children. Time to be a man, fight for your wife, maybe that is what she is waiting for?
