Good Decision?

A guy I started talking to was in a 7 year relationship; they just broke up 4 months ago. As the start of our relationship started to get deeper, I noticed little things that he was holding onto from his last relationship. I thought about it and thought maybe he needed to take some more time to be single and get over his last relationship. I knew I liked him more than he likes me. We talked it was sad. He said he didn't want to leave me but he understood and he would take the time he needed.

Should I just have stayed and waited it out? Or was allowing him to be single and grieve him breakup a wise idea?
