<human>: Can you provide a brief rundown of the text in within 3 sentences?

We've been dating for 4 years, lived together for 2 years but now we're apart because I'm in school. Bf has no job, is irresponsible, lives at home, no ambition and stuff. I really love him and think he has a lot of potential, however I feel like he will never grow up unless I make a major change. We've been on a break for a week with no contact and he's been trying to show me that he's improving [applied to get his GED, hanging out with my friends and posting things on fb he knows I will see] but I am VERY worried that things will go back to the way they were. We've had MANY talks about this for the last 2 years and he tells me he will change, but after awhile he starts reverting back to his old ways. How long do I wait for him to get his shit together? Should we talk at all during this time? I've never been on a break before so I am really confused about them.This is my first reddit post so sorry if I missed anything.
<bot>: on a break with non ambitious bf, showing improvement but I'm worried he'll revert back once we get back together, how long should break be and should we communicate at all?
