It seems that there has been much going on and no real time to settle in. I suggest you slow down and figure out what you are both doing. What are your goals with this? What kind of future is in store?
I also suggest creating a foundation that is stable. Cheating adds instability far beyond make up sex and nice feelings for each other. Allow that time to happen to heal more and pace yourself.
You might want to do a tag search for "lessons" and "foundations." Read around a bit here and educate yourself, "open" is different from "poly" and finding out how might help. Reading up on "jealousy" and "cheating" too. Lots of good stuff.
