As a mature young man in love, you have a very long road ahead of you. Because of your strong faith and hers, I suggest a long engagement, say, two years. This will give you time to get your FILM dream off the ground, save some money for the future, and for the two of you to get used to the battles between religions. You two will find out if you are strong enough to weather the storms. Here's some questions to help you work through your problem.
You've said very little about your girlfriend's perspective in all this. How does she react when her family bad-mouths you? Has she asked you to be JW to make it easier on her? Is she dreaming of a Kingdom Hall wedding?
Have the two of you discussed the beliefs that will bring you in conflict, and have you come to a compromise?
- What will the two of you do if either sets of parents behave badly? Will you support each other no matter what?
- Is she fine with a civil wedding? Are you fine with a civil wedding? Are the both of you fine with relatives and friends refusing to attend the ceremony?
- Would she marry you if you never baptized as a Jehovah's Witness?
- Does she expect you to abstain from blood transfusions...for yourself, her, future children? Could you watch your future wife die in childbirth, doing nothing, because she refuses a life-saving transfusion? Your newborn child?
- Under what religion will the children be raised? Both? JW only?
- Is the JW dream her dream...pioneering for her, "reaching out" for priviledges for you? Can she give up that dream so that you can follow your dream of FILM? Can she live with the sad comments of the women at the hall, disappointed that she married a "spiritually weak" husband who won't "reach out" for more responsibilities at the Kingdom Hall because of his own "selfish" interest?
