At the time, marrying for love wasn't really a reality. So when you say "she wanted to marry", that's not the case at all. Your faction leader likely spotted someone he wanted to make an alliance with, or someone he thought would be a good addition to the family. The girl wouldn't be consulted at all. She'd be told "By the way, you are marrying this guy tomorrow".

Harsh by today's standards, sure, but considered normal for the time period.
