Maybe if this were a math equation or a science experiment, but you're talking about marriage and having kids. That generally involves a lot of emotion, and you're not gonna get someone to feel drawn to you if you treat significant things like some trip to the grocery store.
Love doesn't come from logic or facts, man. You want marriage, you need love. Kids? Kids you might be able to get by "accident" during a one night stand, but you gotta know that if you do that, you'll be a world class douchebag and there's no guarantee the woman will A.) keep the child and B.) let you anywhere near the child if she does keep it.
And if you try to force it? There's folks here that don't take too kindly to that.
