It sounds like overall you've both done an exemplary job of setting this up in a healthy, sensible manner.
I think making sure you have a plan in place to ensure continued good communication is helpful. It's easy to "get into a rut" when we are busy. We are short on time and sometimes that leads to just running through the motions without taking time to REALLY connect in conversation-that can kill ANY relationship!
I understand you not wanting to "jump the gun" on meeting any "others" but I think I would consider that one more. Maybe that would work for you-but I know for some people this could actually create more problems than it solves. So just consider it some more to be sure you are addressing possible problems it could cause, distance between the two of you, miscommunication, misinterpretations, fears, insecurities etc.
Beyond that-I think you are right on track!
