My best friend is getting married in a few months and I am so sad. We have known each other since childhood, and while it is true that I probably hold too high standards for my loved ones, her fiance seems like a poor choice of life partner.

She deals with his unpleasant traits with good humour but admits they argue a lot. They have been together only a couple of years and have had a very short engagement.
