Ask yourself this: Do you really want to expose your future children, to this level of toxic behaviour? I sure as hell didn't, and I haven't.
If you look at your post carefully, what you are truly missing is your pre-Cult family. THAT is what you are missing, not the cult-indoctrinated, heavily dysfunctional family. Sorry to say, you are NEVER going to have that family back again, they are gone, unless they all somehow wake up and leave simultaneously. You are missing a memory. I miss my parents as well. Guess what? There's nothing I can do about it because they all passed away before I was 30. Gone. They live now in my memories, and I tell my son about them and it makes me smile.
The cult family will not accept you as you are now, will be demeaning, judgmental, and belittling of every little thing you do, say, wear, and go. Do you REALLY want that level of craptacular back into your life?
If you grow up more and marry and have children, THEN you can start to have a normal family life on your own, as you see fit, with no WT Cult crap to have to contend with. And if you did allow your parents to see your children, it should always be 100% supervised so that they don't try to indoctrinate them and turn them against you. Think I'm kidding? Search this forum, you'll see it over, and over, and over again.
Trust me on this; the sooner you learn to protect yourself against these types of cults and in particular toxic behaviour (shunning, emotional blackmail, manipulation), the better off you will be. You're enjoying life, there is no enjoyment in the JW cult.
