Yup... this isn't beyond dbing per se, but he has to find enough maturity to work with you on all of this.. dbing won't fix his personal issues, but it can get him hopeful enough to try...
Sometimes dbing works, sometimes it doens't... even when it doens't dbing is the healthiest thing for YOU to be doing anyways.. its a great strategy.. it builds YOU UP while motivating yoru partner to follow along...
Even if they dont, you get build up and can move on
