jgnat is spot on, kari! Online uni would give you not only an eduacation, but fill the time so you can't dwell on the jw's.
Is there a someplace you could get a part-time job? Even Wal-mart? A small office? That would give you some $$ of your own, and be another way to fill time so you aren't dwelling on the jw situation. Plus you would have the opportunity to meet new people and develop relationships.
Do you belong to a church? Are you looking for one? Again, there would be new people to meet and do things with, and many churches are active in the community, so you could volunteer and do some good for others as well as yourself.
Own your life! Please don't allow the situation with your hubby/jw to overwhelm you and run your life. Easier said than done, I know, but so worth the effort of having a life well lived sweet girl!
