What do I look for in a girl? Well, at this point a "Yes" would be the main requirement (j/k....*runs away crying*).
Seriously though, the main thing I look for in a girl is communication. Obviously having similar interests would be a huge plus, but the main thing is for both me and her to be able to speak to each other on an equal level, be able to hold engaging conversations and know that we can turn to the other in times of need. There would have to be an absolute mutual trust (I'm a very trust orientated person; if someone betrays my trust, it's hard to get back - and I expect others to be the same). They would have to be someone I can laugh with in happier times, but be able to stand side to side with in darker times.
As with interests, sharing beliefs and morals would also be a plus. I respect that each person has different beliefs and morals. The only thing I would ask for is that my beliefs and morals be respected, and in return, I will respect theirs. However, the only thing I 100% ask for, is that they wish to have children. I know a marriage that recently ended because one wanted a child, while the other didn't; and I'm definitely someone who wants to have a child in the future.
That brings me to my next point. As @Hide in Plain Sight said; as much as we would like to say otherwise, looks do matter. I know I'm not model material myself, and I certainly don't expect someone who is model material to be interested in me, however, I probably wouldn't look twice at someone who was too ugly xD
