Stacey, I'm really sorry this happened. (((Stacey)))
I remember when you posted about this a few months ago and this is what I said then:

There's always a possibility he's ready to do something different, but that only reaffirms that what you were doing is working. It's too early to change anything yet.
I have to say I still stand by that. Go back to whatever you were doing at the time before you got sidetracked. Don't beat yourself up, it's in the past, live and learn.
As for your friends saying keep on acting like an OW to remind him what he's missing, that doesn't make any sense to me. If he's getting it, he can't miss it. Stand your ground.
