My thoughts: You CAN'T trust him at this point. He hasn't earned trust. It is folly to marry a person you cannot trust. You will be miserable. I hope you will reconsider the wedding until he proves that he has changed. That would mean not using, being in a program of recovery and time. At least a year. Of course, many people have come here in your same situation and we all strongly suggest that they not marry an active addict. Some heed our words and others don't. I hope you will.
