Time to Let Go.....How? (6)

[otw]

I am trying to remove myself completely from communication with W for a while. I need to do this for me.
She sent me a text stating she will be dropping kids swim class stuff off today. I don't feel a reason I need to reply as it doesn't warrant one. Is this rude or fine?

I actually have anger towards her for the first time. I was wondering when it would come.
When she gets here I plan on just being busy in the garage or something and let the kids get the stuff.
I'm conflicted recently as there has been more open communication between us but the events that unfolded the other day about the most likely OM have be knowing it is nothing.

I am looking forward to the weekend even though I won't have the kids I plan on doing a lot for myself. Problem right now is there are a lot of holiday parties going on that means drinking which I am trying to avoid as the next day seems to be a big let down as it is a false fun time and then reality comes back. I am trying to have real activities consume my time.
