How long do I wait??

So me and my boyfriend just recently broke up. We were together for 3 months. I was pissed at first but we talked and I kind of understand. He said that he doesn’t think we are a good match but then he said he would try again. He also said the reason we broke up was because he doesn’t have his life together. Now it’s only been a week and I know I should give him space. And I would like to but it’s killing me to not text him. How do I go from texting someone all day and talking to them everyday to not talking at all. What are some ways y’all would keep your mind at ease. Also how long should I wait to talk to him again. I really do want to try things again with him but I don’t want to seem pushy.
