No matter how much we want to admit that looks don't matter but in reality when we actually have to chose someone we do prefer that someone to look good . The initial stages of a relationship is mostly based on looks cause attraction is necessary to build up a relationship . But the later stages in a relationship needs more than just that. You need more inputs than just good looks to create a high value relationship Good looks can be a natural advantage at least they have less chances of being ignored or being rejected in the first place but as time goes by you know that's not enough ,you need to be more than that . Good looks create confidence which is a good thing but at the same good looking people may also lack self belief ,charm,humour and have self doubts .So a high value healthy relationship needs a bit of both .
Also as we say beauty lies in the eyes of the beholder .Hence what is good looking to you may not be that appealing to me . More than good looks I think what actually matters is a bit of self care ,personal hygiene and fitness .
