I would be lying if the first thing that subconsciously goes through ANYONES mind when looking for a partner is the looks. The way someone looks is 100% related to a healthy relationship. The people who say something along the lines of 'oh i only look for someones personality' is lying. ALTHOUGH-- obviously if you want to start a relationship and settle down with someone it is 1000000% needed for you to get along with said person to have a healthy relationship. So there is no either-either. They both contribute 50/50.
