Two stupid questions. 1. Are you still using? 2. Have you apologized for the behavior?

If it was a good relationship, you may be able to talk things out, take things slow and begin to rebuild that trust. There's no guarantees but it's all you can really do. However, you can't do any of this if you're still using or can't bring yourself to apologize for the secrets, etc.

My two cents.

Be safe.
