"I just would like some advice and encouragement on how to deal."
You've given him plenty of chances. Frankly, he isn't much of a man. Although he's seemed to show you his deeper, truthful side, what he's given you is just another facade. He talks to you about your future plans for togetherness and family, but then he goes to the KH where the JWs plan for a future where all nonJWs (yourself included) will have their heads smashed open as Jehovah drops rocks from the sky.
My advice? Your time and energy would be much better invested elsewhere. My encouragement? This has been a valuable learning experience for you. You can be glad that you didn't spend more time and energy on him.
"He was my best friend in every sense and was always there for me. I still love him so much. I've decided to end all contact with him as it hurts too much to now realize that he's ok with having sex and carrying on with me without committing to me. I'm hurt because he's not the man I've known. He's a stranger now."
You both have changed. You now realize that a best friend shouldn't be treating you like a "dirty little secret", keeping you away from his friends and family. He has changed too because he can't keep up the work required of his double-life.
