I see a lot of rationalizing what you are doing. I'm going to give you the LBH perspective...and that's what I see. No I don't understand it, but if you keep rationalizing that its just a few texts or just one more match, I suspect 2 text grows into 4 which grows into 6, etc. And one chess match grows into best 2 out of 3 and then 3 out of 5, etc.
I know my W tried to break it off with OM a couple of times. She has told me. Then a simple email of hows it going, or did you see this, or something from one of them would just spark and rekindle things back to full blown EA communication again.
You aren't cheating on OM. You can't cheat on someone your not married too, haven't even met, etc. Get those thoughts out of your brain, please.
24 hours, no contact, that should be your #1 goal right now...in my opinion
