I did quit when I was first married. I was too ashamed to tell my wife about wanting to wear diapers, regression and all that goes with it. For several years this worked, for the most part. There were a few times I had to go into the basement and wet my underwear, but for the most part, I tried to separate myself from the desires.
When the children came, I was so busy between job and family, that I could keep the desires buried, for the most part. But when we moved to where we now live, I suddenly had Fridays off while my wife worked and the kids were in school. The temptation was too great and I've been wearing diapers ever since. It came back with a vengeance.
Everyone is different and as was said, we seem to have different degrees of desire and how we experience AB/DL. You may very well be able to give it up and not feel the extreme urge to wear. Like BoundCoder said, give it a try without giving up the supplies or you ADISC membership. See what happens and how you feel and that should give you some idea.
You also could explain to whomever your spouse will be, your history, and say you want to put it on a very low key level, something you might occasionally do but not obsess over, especially on a regular basis. A number of our members do that because their wives don't approve. There are a number of different workarounds regarding this as a lifestyle.
