I'll just join the throng and say that it sounds like you did the right thing...especially after how you describe how H approached you on it!
For a long time in my sitch, I both initiated and accepted intimate contact with my H (although in no way could it be characterized as ML) as a means to try to restore a real connection between us (based on things he said over time about wanting to be with someone who wanted to be with him...and on my LD tendencies). BUt now that I have more knowledge about the timeline and depth of his R with OW, and realized it was making no impact whatsoever on him, and not providing me with much either, it has made it a very easy choice to back off.
Hope you have a great day, and aren't getting all the stormy weather we have been lately!
