I'm not going to tell you what you should do, but I don't agree with asking for those words before your xH is ready.
DR talks about NOT doing status check in one of the chapters, you run the risk of making your xH commit to something he's not ready for.
I say sit on it and continue to do what you're doing. Draw him back into the R with you, and give him time to feel comfortable, without pressure, first.
