I already know that this paragraph is unclear, but I want to know why others find it unclear. There are basically no passive constructions or anything of that nature. As far as I can tell, the phrasing is not awkward except for the last sentence possibly. What exactly am I doing in this paragraph that is obscuring the message? I don't think it is because the sentences are too complex either. I did not even try that much to achieve rhythm. Maybe the context is not clear? But you did not interpret my words correctly, if you believe I wanted to be more than friends with her. For when I wrote about her personal and physical beauty, I wrote about my feelings for her in the past, in the days before I knew she had a boyfriend, in order to demonstrate that my pursuit of her was pure from its beginning, because through that pursuit came my desire to be her friend. For Marie doubted that my intentions were pure, not only those from the present, but those from the very beginning, and I discerned this. Therefore it behooved me to establish my true intentions, to show my present integrity through my purity in the past.
