Should I wait for him?

my boyfriend broke up w me after 6.5yrs to 'work on himself" . We lived together for 3 years, it's been 2 weeks since he moved out & I've seen him twice after the breakup. He still says he loves me & wishes we could be more but we "cant for now until he betters himself" hes cold over text but very lovey in person still. I haven't heard from him in 2 days. He never cheated & we've never had trust Issues. We were together since I was 14 & he was 16 . I think he might be going through something mentally that maybe made him leave out of nowhere ? Any advice would be great!
