What should I do?

My boyfriend and I got into a big fight he told me he was done. He caused the fight by being insecure and he accused me of smiling at me phone and texting another guy.  We do this often where we say we're done but aren't. We haven't talked in about 3 days last time we texted I text him first. How much longer should I wait to text him? Or should I wait to see if he will text me?
