I'm so sorry you're going through this now. I was in the same situation as you... Raised in, every single friend I ever had was a JW, as was my husband. My kids had been raised in all their lives. My friends went from being very concerned, to being pushy ("what can I do to help you get back to meetings?") to ignoring me. I thought my life and my marriage would never be the same.
It's been over 3 years since I was to a meeting last, and everything has finally settled into some sort of normalacy. Some friends still avoid me. But some, when we're forced together in some social setting, treat me like they always have. We have fun together like we always did. I KNOW it has everything to do with my own attitude. I'm not apologetic anymore, afraid they'll ask me about meetings... I am who I am, and they can see that I'm happy and confident. So they respect me and I respect them (praying before eating, etc), and we enjoy each other.
You say you're worried about not being the husband and father you used to be. Why are you worried about that?? That person spent umpteen hours at meetings and service and studying. You have time to spend with your family (when they're not at meetings), you have the freedom to discover the person you really are and what you really believe. You are a better person now without the mind control.
Is your life going to be different? Absolutely. Your marriage? Yup. But I believe that marriage is always about compromise, JW or not. Your wife and kids believe differently than you. That's ok, as long as they respect you for who you are now, and you respect who they are. I absolutely hate the fact that my husband wastes so much time and money going to meetings, service, assemblies, etc. But he hates the fact that I don't go with him. And we have found a way to live with that - because he's a good person and I want my kids to have a happy home to come to when they are grown and have their own families.
I know it doesn't work for everyone. But if you can convince yourself that you deserve to be treated with respect, you'll project that belief, and it will affect others' treatment of you. Maybe that's a good thing to start with?
