@Perky That myst be some heavy weight that you got off your shoulders. You've been brave and I wish you all the best.
I do not want to discuss your ability to actualy stay off NBE in the future, more or less everyone I know who tried NBE sooner or later "relapsed", but I must suggest that you should at least resist the first time the chance arises.
Let me explain and keep in mind that, although this is from my personal experience, I have seen the same pattern in other couples. Your wife probably has questions now. Transition is the obvious one, but even if you say no, society will say otherwise. At some point she will want to put you to the test, and that could be almost subconscious even from her point of view. A time will come, probably in the next couple of months, when she'll say something like "As long as they don't get bigger than mine..." or "Don't worry, I am OK, with it if you want a bit more." Or somethign along those lines. That's the test. Don't take it as an excuse to restart or to think that you can just get a larger set and then "blame" that on her. It's a way to prove if you think it's more important to be "normal" with her, or if it's more important to grow boobs.
I know that right now you are 100% convinced that you can and will stop. Hold on to that feeling and, most importantly, hold on to the feeling of relaxation to not having to hide anymore. Let things cool down and, if in the future you'll feel a strong urge to restart, look into yourself and find that "normalcy" feeling again, gauging how good that felt VS the feeling of further growth.
Good luck and enjoy this moment of bliss. I am sure your wife is as cool as it gets and you should be happy and proud to have her next to you!
