Wife checked out (3)

[2ltl2lt]

This saturday WW texted me saying she thought I was leaving S with my mom too much on the weekends. He has only stayed over a couple of times in the past month. She said something like I need the first option to take him if you don't want him. I called her and said that I have been taking care of the kids pretty much on my own and felt like it was going fine. I said that the kids enjoy spending time with their grandmother. She is worried that my mom is talking bad about her to the kids. So I told her that we need to agree on a schedule if this is going to be a problem. She has been avoiding this since the beginning.
