I really just feel like such a fool!
I don't think so. It is difficult to understand our own motivations, as it is that of others. The entire dynamic of marriage is difficult too, particularly once there are children to consider. Mix into that how you are dealing with the toxic upbringing of both of you being raised as JWs and how it destorts perceptions of reality and morals. Your post makes you sound very caring, rather than coming across as a fool.
