I think you are in a good place. I think you have a long way to go on this journey, but I would suggest starting by learning to earn each other's trust.
How you ask? By caring for one another and allowing that to build for a bit of time. What I'm saying is that you two have hurt each other. H hurt you more. He needs a chance to not only build that trust up with you, but also to learn to make that a normal part of his life. While he fights his addiction.
Time to build trust seems important to me for some reason. Not just building it, but taking the time to build it for a strong foundation in your relationship.
Likely would be a fun time for the two of you as well.
My thoughts. I'm not in your place, so you'll have to bear with me. You may want to post over in piecing together as well.
My thoughts and prayers are with you and your family Kassie.
