Our bodies are doing the same thing...My H will be out of house two months tomorrow...he probably doesn't even realize it! He was so nice for two days and now we haven't heard from him in two days.
Do you feel like you are forcing it, just going through the motions with your kids? I feel like that right now and it really is bothering me!
I will never tell you any of the things that you mentioned above...my best friend of 30 years says them to me on a daily basis and I know she means well but it kills me! Let them spend a day in our shoes!! I would not wish these feelings on my worst enemy!
