Inquiring Mind,
Well, I want to ask, "Have you spoken of life 'issues' with your JW intended."
What does he tell you about your wedding, surely he knows you two can't be married in his Kingdom Hall. He will also be viewed as 'spiritually weak' for marrying outside the Watchtower Bible & Tract Society. You say he is a long time witness - does he hold a position within his congregation?
Have you discussed how your children will be raised. If you go along with the children being raised as witnesses, are you aware there will be no birthday celebrations for them... No Christmas... no Thanksgiving gathering... No Easter...No Independence Day celebration, no acknowledgement of Mother's Day, Father's day; the list is endless.
They will not be permitted to participate in 'holiday' activities at their school, and also will be discouraged re participation in ANY activities, such as Scouts, sports, 4-H,YM/YWCA, and much, much more. Is this the sort of upbringing you picture for future children?
Sincerely, InquiringMind, you do need to 'inquire' further - and ask your 'intended' about such things.
I'm sure others here will have some additional suggestions/questions for your consideration. So, keep reading and posting your questions.
