Hi Wendy,
NO... I am not married or dating a JW...but I was married to one while I was a JW myself. Most do not leave....even if they don't attend their meetings often. Whether a "weak" JW....or a "strong" JW.... the doctrines are deeply imbeded in their heads.
I don't know your feelings for your boyfriend.....or how much you care for him...but you have to think long and hard about what it entails for you. If you think that the eventuality is that he will leave his faith...the odds may be more against that.
It will effect every facet of your relationship and your life. You will have to contend with holidays... birthdays... patriotic events... and if he should get more involved as he gets older than it will causes a huge rift between you. Children are another whole matter to broach.
Being a JW is not just a belief system...but a way of life.
Where is he at in regards to being a Jw?
