I remember a conversation with my aunt a few years ago. Okay several years ago. She told me that there were times when she made sure to vote just to cancel out her husbands vote. I remember thinking, "How in the world can you love and be married to someone whose political leanings and ideals can be so opposed to your own?" It made no sense to me. Then several years later, I fell in love with a republican. Through that experience I learned that such an experience is very much possible, however it can only work if neither are particularly political. Sadly, that was not the case in my relationship. He began to act more and more conservative just to pick fights with me. Like I said, heated discussion and debate is one thing, but it became constant fighting. On subjects he didn't particularly care about, just because he loved my passion on social issues. I couldn't take the constant disagreement and fighting anymore. That being said, I can see how such a relationship can work. Mutual respect for each others opinions and ideas, especially if you don't agree.
Every single successful marriage I have seen has been when the husband and wife are partners. It is when one places themselves over the other is when problems arise. Now, this is just the marriages I have seen and experienced in my group of friends and family. I am not saying a marriage where one spouse is "above" the other can't work, just that I've never personally seen one.
