Hi Es,
Bottom line: you will have your own family to look after without having to continually worry about the one you came from. JWs are always stressing the importance of headship () well, you jolly well say you're following headship by doing what your husband wants (). They can't have it both ways. You HAVE to move on now. It isn't easy - goodness, just look at what's happened re my own family - but we cannot be tied down by emotional blackmail.
If your parents don't attend your wedding or don't want to associate with your fiance/husband then it's THEIR loss. I'd also keep your child at a safe distance from your parents, too. I know that sounds unkind, but we all know what they want to fill his mind with!
You're a brave girl and I know you'll come through this ok. You also know you're always in teh right place here, amongst true friends.
Love,
Ian
