Mizalisa when you met your boyfriend you had no inkling of how irrational the crazy cult of Jehovah's Witnesses is. Of course it was not your fault just unfortunate.
Certainly the conflicts that you are now aware of are worthy of a film script and indeed there are such. The British film Apostasy 2018 by Daniel Kokotiljo got rave reviews and if you saw it would give a vivid insider's view into some of the conflicts JW carry with them.
Three points to consider:
1/ Your boyfriend has no money to be independent-- perhaps for a year or two?
2/ He has no family support with you or his writing in mind. In fact his family, given the chance will want to obstruct his life choices and then they will shun him when he leaves.
3/ An ex-JW, UNLESS he fully understands the scale of mind control he has been under, and has a genuine grasp of the errors of the JW organisation-- even some years later on when under stress, he may want to return to the fold and possibly try and bring his partner with him.
As a suggestion you could ask him to post here as you have done, in his case it would be a matter of his loyalty to you. If he refuses because he has been told this is being unfaithful to the cult, then it is fair to say that he is still subject to their brain washing.
All the same sorry to hear your predicament but a lot of us on this forum suffer from the draconian rules of the JW cult practised by our family members even if we have left many years ago.
.............Stephan's suggestion is good, for your boyfriend to leave home would be a good indicator that he has initiative and wants to be with you and possibly that he wants to leave behind his old life.
And last suggestion: try another boyfriend-- JWs are always trouble!
