He doesn't want you to work because it would give you independence, you would have your own money and he would lose some control over you. It has nothing to do with another guy, it is a red herring, he only cares about booze...IMHO he will start drinking again as soon as his legal issue is resolved..he is not in recovery...if it were me, I'd start looking for a job, even if it is part time..your son can go to a public school, make some new friends and expand his horizons.
