Friendship/ Marriage

The question that was asked in class was if friendship was based on similarity or differences. I feel that marriage is a different type of friendship, but some people say that marriages work oppositely, as in the opposites attract. I was wondering if anyone could explain this because in class I felt like we came to a conclusion that true friendship is based upon similarities. To go out to eat, you would need to like the same food, to go shopping together, you would need to have the same styles, and to have reasonable conversations and not come across arguments, you would need to have the same ideas and morals. So maybe the saying that opposites attract is just a silly saying that isn't true..?

We also talked about the disproportion of love may work for some people, but would this be a form of "true love"? What I have come to realize is that people always want what they cannot have. Not trying to bash boys, but in my personal experience, it has always been a boy! If this remains true in relationships, then the relationship will either stay unbalanced, which may lead to an unhealthy relationship, or the higher person in the relationship will finally give the lower person what he/she wants and then once the lower person has what they want, they will become uninterested. If that is the case then maybe it could be considered a friendship, but not in the truest form. In the conclusion, I am not sure if I agree that a disproportional relationship could work, or at least stay healthy. Maybe it's an exception not the rule, but it is definitely something I have wondered even before we talked about it in class.
