5 months is a drop in the bucket to cut your losses. I don't mean to sound harsh, but after you get married and have kids it only gets worse. The longer you wait the the harder it gets, sound cliche, but it's that way for a reason.
My .02 is save yourself first. Completely understand what the JW organizational is really about. Be prepared to back up your research scripturally. So when you do get into a heated discussion you don't get twisted.
Also, loving someone because they serve God is definately NOT wrong. That's a great attribute. However, in this context, you are both serving the GB as long as you believe in JW; which is a TOTALLLY different story.
God Bless
