Wow....I would have a few choice words to say to that husband. Who is he to judge what YOU need. You do not need his permisson nor do you need his approval to do what is best for YOU! You sound like you know exactly what you need, DO IT. If he doesn't accept that you may need help then he is NOT the man for you, accepting someone, flaws and all, is what marriage is about. I will be honest, from what you wrote he sounds too controling and is out of line with his behavior. 2 years seems awfully quick IMO to go of your meds, fall in love, get married & then find out he's an a.s.s.
There should be some places around you to help get sliding scale meds. we have low cost clinics here, check into that too....
Good luck and please keep us informed.
