Should I contact my ex after a month of no contact?

Rocky relationship. Bad breakup. He was dishonest. Said hurtful and mean things when I confronted him. I said nothing but to leave me alone. Been almost a month since we have talked. He sent me an email right after the break-up saying that I destroyed the relationship. Now that time has passed and Im not as angry I feel like I want to get some stuff off my chest as we have known each other for 10 years, he was my first romantic relationship and man that I loved. He was my best friend. The other side of me is saying to wait for him to contact me especially after the way he treated me, but Im not sure that he will. I have said nothing and feel I need closure or something. Should I even bother?
