Hi curiousabouthim, and welcome to the forum.
Are you aware of how jws view women? They practice the headship principle, as outlined here at 1Corinthians 11:3
But I want you to know and realize that Christ is the Head of every man, the head of a woman is her husband, and the Head of Christ is God.
If you marry this jw, he will be regarded as the head of the household, with the right to make final decisions on child rearing etc. Are you prepared to accept this? If he feels that your future children should be raised as jws, and his fellow jws will pressure him to do that, are you ready for the inevitable conflict that that will bring if you disagree with him? He will also be under pressure to bring you into the congregation, are you ok with that?
Whatever he is saying now, those things will be in your future. If you are fine with that, then stay with him. If you are not, then I would think very carefully before you commit yourself fully.
