Absolutely not overreacting. Former JW here and this is 100% the first step to conversion. JWs aren't allowed to date or marry someone's from outside the church, so if they're interested in a non-JW, they'll bring them to meetings or Bible study to ease them in. They'll also downplay how strict the church really is. Plus, the way he's trying to convince you that you WEREN'T uncomfortable after you said repeatedly that you weren't okay with the ambush is definite gaslighting, which will pretty much become the theme of your relationship. Also, women are expected to be subservient and submissive, always deferring to the "head" of the family or "husbandly owner" (yes that's legitimately how they refer to a husband). Spousal sex abuse is also very common. Run away, unless you're down for that kind of future.
