I am a guy. I don't throw stones, but some do. I will use a movie quote that I think is appropriate. "Why is it that men always feel compelled to chase the ones that run away? Immaturity!?" I think that in youth, It doesn't matter as much. As an adult entering into a life long bond, it matters alot. Before such a commitment, men want to know that there will be no regrets, and that they are THE special one. I think men are more cautious than women about entering life long Relationships.
