If you've made your apology and it was sincere, leave it at that for now. Anymore would show him pursuit, and neediness (ie you need him to know your sorry).
It took on average 3-4 months for (x)W to want to talk again after these types f issues would creep up. After a couple times of me not reaching out to her anymore, she came to me, and well, things a very good now. It's just all about showing them, "hey, fine, that's how you want things, then that's how they'll be, my life and life with everyone else in and around the situation will go on weither I talk to you or not." Then they get to thinking, 'heh, I really messed that one up', and then you'll be receiving the apology.
