Kudos for achieving POMO. That is the biggest hurdle for some JW escapees.
If your wife and children still enjoy being connected to the JW world in some ways, and if their involvement is relatively healthy tolerable activity, it is possible to happily coexist as a family.
Ideally, you would simply become the "unbelieving" yet admirably loving and tolerant mate/parent. There are many families with that dynamic. Most husbands/fathers in that category often command greater respect from JW authorities than is given to a PIMI husband/father.
If a "religiously divided" family has a reasonable level of domestic peace and happiness then the wolves of a JW congregation generally back away and retreat, dropping in from time-to-time with some routine love-bombing.
Avoid giving JWs the impression that THEY must act to protect YOUR family from "spiritual harm", because that is when JWs feel obsessive-compulsive obligation to pry intrusively... with the intention of 'protecting one of their flock'
If you eventually lean toward unilaterally disolving the marriage, some adamant religious opposition from you will, ironically, cause JWs themselves to help put apart the marriage for you as they attempt to "protect the spirituality" of your wife/children by endorsing a 'scripturally permissible' separation.
The situation of Michael Wayne Moore demonstrated what can trigger JW stormtroopers to attack. If you pursue that route, it will be rough, so prepare everything in advance.
I gather you are intelligent and were already well aware of these things.
