To be or not to be: head over heels in love or rational love?

My opinion concerning this question is always changing depending on my mood. When I was head over heels in love, which was just once in my life, I didn't control my behavior, my actions, sometimes I was rude with others and it was extremely difficult to overcome this condition. I thought that this is the only way love can exist and I didn't want it ever to repeat. But now, generaly, I'm convinced that love should be rational.I think you may only create firm relationships, a family when your mind is clear from chemical reactions caused by love. It doesn't mean that the marriage is just a cold count but both people should be responsible for that decision, they should be aware that they will be able to live peacefully together, that they are ready to live through thick and thin. In case of overwhelming feeling of passion which sometimes can be confused with love, the relationships can be destroyed by troubles.
