He keeps reaching out!

My child’s father and I were together for about 2 years. He broke my heart over the weekend and I strictly want to just focus on our son and coparenting. He keeps reaching out to apologize. His apology means nothing to me and I believe he’s only saying sorry because he was going to get caught. I sent him this message, is it direct enough that I don’t want anything else from him besides being a good parent to our son? I am trying to put my feelings aside and just think about our son.
