You're looking for a man that really really wants to get married? Lol... I would say most men need a bit of a push towards it. If you haven't really talked about how you feel about it seriously, more than casually mentioning it on a car ride, then immediately shutting yourself down when he didn't have the exact same opinion as you, you need to make it clear that it's important to you... your fuck up here is expecting him to take small talk from a first date, and a short car conversation as you telling him you seriously need something.
