The WTS has designed things to keep people in place. Pressure from the family to remain, perform, etc. It is part of the indoctrination process that they have down pat.
Here is a general suggestion for you to consider. It's the middle ground. I will be implementing this myself.
1. Confirm your love for your wife, and assure her to a point that she is comfortable that your problems are with the WTS not her, and you have no intention of leaving her or your relatives.
2. Go to the meetings as you can, be nice, don't rock the boat. Don't share your personal views with the people there. She wants to be there with her husband, not alone. Fill the need. Don't badmouth the Society to her. Over time she will accept what you want to do, and you will be able to go less and less as you like. You can share with her, in an informative way the things that you have realized and feel about the WTS. This should be done in an atmosphere of normal sharing between spouses. Keep negativity out of it. let her know that you are just thinking for yourself.
3. Once she is comfortable with things, help her to understand that this isn't for you, and you want to do other things with your free time. Nothing negative. Just that you need your time too, like she needs her time and she wants the Meetings. You don't stop her from the Meetings, and she shouldn't try and stop you from what you want to do. Mutual respect for one another.
You and your wife are involved in an Organization that has a structure in place to control people. It is going to take time, perhaps years to free yourself of it, and maintain your marriage. It will take tact, and patience. You will have to sacrifice some of your personal perogatives for the sake of your wife. Just be good to her. You will need one another. Have faith in her and trust her. There is something between you, thats why you got married.
