I can't say for certain because I don't know your H but I can tell you what worked for me(my H also used drugs and had an affair).
Really, you are starting at square because you haven't rebuilt trust. Here's a list that comes from the survivinginfidelity.com website.
In order for your marriage to successfully survive these are some things that your spouse must do:
He must be totally honest with you about everything He must answer every question that you ask truthfully and fully. He must do everything in his power to prove to you that you are the one that he wants to be with. He must prove his love to you...he must be patient, gentle, compassionate and understanding. He must feel your pain. He must fully understand the devastation that he caused you. He must accept full responsibility for his actions. He must stop all contact with OP and not try to protect them. He must reassure you that it is OK to ask questions. He must reassure you that you will not drive him away by doing the things that are necessary to heal. He must recognize when your struggling or experiencing a trigger and comfort you. He must be able to tell you how sorry he is and show you. He must re-enforce to you, that you are not responsible. He must put his own feelings of guilt and shame aside and help you heal first. He must reconnect emotionally, mentally, and physically with you and stay connected. He must work on rebuilding trust. No secrets. No privacy. He must be willing to seek counseling. He must learn what is and is not acceptable when communicating with the opposite sex...he must establish boundaries and not cross them.
I needed my H to affectionate but honestly, it was a really hard road because at times, I was downright disgusted with him. You have to let your H lead the way. Ask him what he feels comfortable with. If he tells you to back off.....BACK OFF.
It takes a LONG time to regain trust and every single slip up, sends you right back to the beginning. Focus on your recovery. Show him that you can do this. No relapses. I know that it is easier said than done and I know that I am not the one sitting in your position but you have a choice here, you can continue to relapse and be untrustworthy and lose your marriage or you can stand up and fight.
