I stopped wearing mine after T-giving...mainly because H stopped. Since we each would now and again take the rings off for chores or weekend activities with the kids, I don't feel it's that big of a deal...except when I noticed he stopped wearing it daily. Even then, it won't really be a huge deal until we officially announce publicly to our family and friends. Right now, as juvenile as it sounds, on social media, we both have 'married' as our status. It's pathetic that this is our indication of where we are in our marital journey: married on social media.
It's a confusing and sad time.
So, your mantras are good. My daughter's obsession with Elsa and Frozen was prescient. That song!
You deserve better (W needs to finish being a work in progress). Your children will be ok. You will be ok.
