I find myself in a similar situation... however, all I can say is that a marriage/relationship takes work.. and with an addict, it is even more work. My wife is committed to working her recovery, and we are committed to working our marriage. Will it be difficult? Absolutely! The destruction and distrust that developed during her active addition has seriously underminded what was a good relationship.
I have no illusions that a divorce may be in the future, but it is for just about anybody, but i prefer to keep looking only at today... knowing that my wife and i are willing to make it work.
Best of luck. And of course, seek marriage counseling for both of you, and if he is unwilling, at least for yourself... a lot can be learned.
