JaMu, the sensible response to your request for help is that you disentangle yourself from this relationship. To pursue it is to sow the seeds of unhappiness.
You are unaware how far reaching and disastrous the JW influence is on family life. You are unaware that the cult demands that a JW is required to put loyalty to its governing body above the value of life itself as demonstrated in their prohibition on blood transfusions to save life. This is a sobering thought that if you marry a JW they imagine that Biblical precedents determine what we should do today. The JW cult still lives with an Iron Age mentality. You are unaware of the fact that most families infected with the rules of this cult will be split apart at some future time with the loss of happiness and security which family life normally offers.
Finding a suitable life-long partner is hard enough without having the JW organisation muscling in on your relationship. Believe me you will not prosper with a JW in the long run.
On the plus side you have experienced a sort of relationship with one unsuitable individual, I really think you should spread your net a lot wider and find someone who will be happy to put your mutual interests ahead of Biblical dogma.
Life is hard enough without inviting this imbecilic religion into it.
