Princess you don't have to run.
A non-jw I was dating was the reason I was able to get up the courage to finally leave.
I had been "bad" and secretly dated lots of "wordly boys". I was even convinced every time that I could convert/save them, and in time they would know it was the "truth". The thing I realized was, I didn't even know if it was the "truth" so how the hell could I convince someone else. It was eventually this double standard in my life, pointed out to me by the non-jw I was dating that got me to really think about what I wanted for a change.
In the end it wasn't a preacher coming to talk to me that convinced me to change. (I had had non-jw boyfriends try that tactic with me too, that only made me go into attack mode.) It was just him pointing out to me that I wasn't doing what my religion told me to do, if I couldn't even follow the simple rules how happy could it be making me? He was so right.
If you really are attached, don't run, but it's not going to be easy by any means. You need to ask yourself if he is worth it, if the young relationship you have is worth it, etc. Because you are going to have to fight for it. And it's not going to be pretty. But who knows he might actually come around, and you could be the one to end up saving him!
Best of luck to you on whatever you choose!
