Well, W has gone full circle now. She texted me asking if D13 could watch the other three while she went to a cookout, and I said no. I said it wasn't fair to keep them guessing while we wait for her decisions. W said she had decided, and chose divorce. So, I said, well that's definitely a no - I'm not going to keep getting their hopes up, and causing confusion. I said once the divorce was settled and things were maybe figured out, I'd reconsider.
She started pitching a fit saying that it was my choice to not let them see each other, and I simply replied, 'Who's choosing to end our family?"
She then spewed for awhile, so I called her (no more texting!). She didn't answer, so I left VM and told her I wasn't upset, and I loved the step-kids very much, but her choices were her choices.
I reminded her that I had agreed to sign the divorce, and I wasn't fighting her anymore, so all decisions were in her hands. I told her I needed to move on to a new chapter in life, and wished her the best.
I feel good. At peace, ready to let go. I'm sure I'll have rough moments/days ahead, but I know they'll be blips in the road instead of being the road itself.
