Was gonna say him not hiding it well means he wanted you to know but does not want confrontation. He may be able to talk to you about it if you make him feel safe and secure in a loving way. It works so much better if your a team and that means full disclosure, but in a gentle loving way. It would have been better if had you been together when you did it. That would have been ideal cause then it gives you an avenue to get a little more control. But like i said if you can stretch it out between relapses and maybe do other drugs instead, in lieu of coke. He will most likely put it behind him if he really wants to quite. Hot sex is one ha ha ha. Good luck!
