I agree with ric3, the TINDER thing is a pain.
Right now you really need time to kool..
I can say this cause I went thru the same thing..minus the kids.
Take time for YOU. Do something that you LOVE to do and do it.
Her finding out your dating is tricky. She can use that against you in custody.
In some respect just go off the grid for a bit.
My ex and I had an agreement that after I move out that I could leave some of my things there until I found a place to put them. I had a key to the house and she was fine with it.
BUT after she realized that I really didn't want to see her anymore, she changed the locks and I really became amazed at just how someone that wanted the same thing turned.
What you have to do now is show that you are putting yourself back together with the kids being #1.
If you start dating off TINDER or any site..she could say that you are unfit.
