what he needs is a job, pay slips and some savings
but some people have managed to get their partner a spouse visa while unemployed, claiming benefits and having no savings, but many more have been refused because how can he support you, if he has no job or money ?. very risky .
i don't think it matters if its a public fund or not, as he is claiming it not you, your not allowed to claim public funds, and he has to watch he doesn't claim more money because you're with him when you get to the uk.
