Would anyone be willing to cast a free spell for me?

I would like for my boyfriend of three years and the father of my son to commit to me completely. I would love for him to become infatuated with me and only me and decide that he would never cheat on me. I know this sounds crazy but, I do believe that spells work and it isn't messing with his free will since we are dating, I just want to ensure that he won't ever cheat on me. Please can someone help me?
