Most Helpful Guy
From a relationship coaching perspective, the answer is: all things considered equal, yes. This applies to girls and guys. In other words, no one is going to be in a relationship with someone that they do not find attractive. I've done relationship coaching for 10 years (500+ clients) and I have yet to see it. BUT, if someone meets attractive people and some of them have wonderful personalities while others have ugly personalities, they will pick the person with wonderful personalities even if they are 'less' attractive than those with ugly personalities.
We can't invent chemistry and thus the idea that someone would (happily) be with someone that they did not find attractive but who had a wonderful personality is not realistic. The last thing that I would add is the beauty is in the eye of the beholder.0
