I think it all depends on the individual. Most people need to have some sort of “like” in order to commit to marrying someone, but there are those (beleive it or not- I know people like this) that marry based on their logic. If they see that a respective spouse is everything they want and everything seems to match but the emotional connection is lacking (obviously the person in question doesn’t repulse them), they might go ahead and marry them. These people are usually the type of people who never felt emotionally dependant on others and in general look at life from a very logical prespective. They are the minority.
