Not sure of your ages or stages (kids?),but here is the thing.A lot of people go through a phase when they are partying and being pretty silly and irresponsible. Then they GROW UP. Unless your wife and you are still in your early 20's, you have probably become fully mature adults and have literally left that part of your childhood behind.
If there were actual problems beyond youth and immaturity, deal with them proactively (a-anon or doctor or therapy or whatever is needed).
People often turn to religion when they WANT something to change. That might well have been a decision that preceeded her involvement with the WT org, it was jus the vehicle she used. you are grown ups now.Hopefully, the silly stuff is over in any case.
