<human>: Can you give me a shortened version of the text?

First off I am new here, so don't be too mean to me lol but, My boyfriend of a year and a half and father of my child said that he has thought and does think about cheating on me, but he doesn't want to ruin what he has with me. He said that he just feels like he needs something different sometimes, that he has never really been a one chick, long term relationship kind of guy. I guess I just don't know wheather to be happy he doesn't want to ruin what we have or be upset because I know very well if he was cheating I'd never catch him, he would be too good at covering his tracks. It's really been messing with my mind because I really lost all the trust I had for him when he told me that, I guess I just want to know if I should believe he hasn't cheated or am I right to worry that he has or will soon.
