Hello and welcome, lilwolf. Wow! How was it that he married a non-JW? I thought mixed marriages were VERY discouraged in the society (I should know, I tried to marry a JW ). Anyway, there are a few key things to know:
+ know that he may leave you outright
+ know that he/WBTS might rope you in. Get to know some of the JW doctrine to prepare yourself for the inevitable. We've all been there--it's not difficult to give into the extreme pressure gradient of joining the society.
+ know the vows you and your husband took--"for better or worse, till death do us part". (is that about right?)
+ know that the WBTS teaches a hidden, separate vow: "...til death {or fornication} do us part..." In other words, cheating by one party or another can break the marriage vow. (Also know that that is a novel tradition NOT taught by Christ or the early church.) What that means is that if push comes to shove down the line, if he should someday cheat on you, that would break the marriage bond with God and he's miraculously be free to marry again. Or, he may put you in a situation so deprived that "cheating" is encouraged on your part.
+ know that you may be able to save him. You see, the fear levied agains the rank-&-file JW is so severe that it's almost impossible to leave. It's a very bitter reality, but hope is not lost. There's lots of great folks here to help you work through it, so get your lasso ready. You're actually at an advantage because you have access to more information than your husband does. Keep in touch!!!
