Should I leave for 3 months to a different state to make some extra cash and leave my husband?

We have been having some trust issues reguarding the woman he talks to via internet and his honesty. i also have concern as to the guys he drinks with and where. Things have gotten better within the last month but im afraid if i leave all progress will be lost and we have worked so hard to get here. I feel as if i might just be paranoid.
