Camay,
After a four year commitment this guy should have at least proposed marriage. Then again, if he married you, a non JW, he'd be considered spiritually weak. Hey, my hats off to the guy, if he can be in the same place as you over night and not get involved in "the business" then he's a stronger guy than I. Not that I myself approve of fornication, but was guilty of it before my marriage (with my then JW wife too). Spiritually speaking, marriage is the answer, that and getting as far away from the JW's as possible.
I like the calling the PO deal. It will force him to commit one way or the other.
Just my humble opinion,
Yeru
