When I married my AH, I thought love and our marriage vows would "fix" him. I also was not very educated about addiction and didn't fully know what I was getting myself into. Since we married almost three years ago, he has been to impatient rehab twice and today, he is right back at it again. You obviously are an adult and you make your own decisions but my advice is to NOT get married right now and to learn as much as you can about the disease of addiction. It doesn't mean you have to completely be done with him if you are not ready for that yet, but I would hold off on making it official at this time. YOU deserve more and right now he can't give you that. Good luck to you.
