He may not remember saying that...my H tells me now he truly didn't remember things he said during his drunken bouts...but that probably he was telling what was deep inside but couldn't let it out at the time.
I would wait until just a day or so before the court date...ask to speak to him person...this is what I did...this way you know OW isn't in the way of what is being said.
However, be prepared, even if things are delayed or called off, as I had requested because I told H I wasn't ready...it doesn't mean that H will be ready to work on anything (this was my reason for filing the second time...and the second and subsequent delays of the divorce were more mutual)...
If you contact too soon there is no urgency on his part to speak to you...that is my opinion....stratigic planning in a way...
