You have to ask yourself some difficult questions:
1) Do you love him still?
2) Are you willing to set aside your anger for a couple of hours to attend a counselling sessions that could possibly lead to change?
3) Does attending the session with you pose potential harm for you?
4) Are you just really fed up with it all and need a break?
It is possible to stay sober and change, but often relapses are part of the recovery process and valuable information can be gained from them if the addict is serious about recovery.
A wise lady told me once if I am unsure of what to do don't make any drastic decisions.
I suggest a bit of soul searching, self care, some fun if you can muster, and maybe go talk to a counsellor about it!
