Wow, that's a very individual decision, it's not something that someone could answer for you. Many have stayed in such a marriage and been happy, others have struggled and wish they hadn't. Some questions you might ask yourself:
How comfortable will you be having your children raised in something you don't believe in? It's one thing to deny your children sports, holidays, birthdays and higher education when you believe in it, it's another to see them missing out for no reason.
How does your wife feel about being with an unbeliever and having to go to the meetings alone? I was a JW married to a disfellowshipped person for 28 years. It was not a great time for me, I was often lonely and never really felt accepted in the congregation, I wouldn't wish that on anyone.
How strong is your marriage? Can you see yourself happy with someone else? Will your wife possibly leave because of this?
How committed are you to remaining inactive (as opposed to DF or DA)? Do you have other family you would loose if you get disfellowshipped or DA? Are you OK with living a JW life (no voting/holidays/birthdays)?
Is there any possibility you could get your wife out? It's not easy, but some have done it.
