"all I need to know now should I really do it"
What can it hurt? He has already blown you off. He is already going to get on with his life - with his good lil' JW girlfriend.
I say - throw a monkey wrench into his 'plans'. He ain't expecting you to do anything... now's the best time to do it.
If you make enough 'noise' - he gets into trouble with his 'church' people - and his girlfriend.
Poetic justice, if you ask me.
Plus - it may make you feel a tad better. Then it's time for you to move on. Eventually, you will get a new boyfriend - preferrable a non-jw. No use in repeating the experience, eh?
