Welcome. I can really relate to your post. You are doing it right. You have totally come to the right place. Literally and figuratively. You sound like the two of you have made a well reasoned decision and love each other dearly. The best advice I could give is to feel free to ask any question that comes to your mind when he comes home. I have found that my imagination of what my wife's relationship with her boyfriend is like tends to be much harder to deal with than the actual relationship. If you're wondering about something and it's eating at you, speak up, ask him about it, and allow yourself to feel whatever you feel. Bringing those things into the light makes processing all the emotions you're sure to feel much easier.
Best of luck to you both.
