Sperry, welcome.
This might be a good time to have some space between you, for him to try recovery without the distraction of a relationship (that is about him, by the way, not about you) and for you to decide if you are willing to risk your own recovery while he flounders in his.
Crack addiction can be tough to beat and take time. While he works on this maybe open your life to more meaningful ways to spend your time and building a healthy foundation for yourself.
Others will be along to welcome you but I wanted to say hello and say I am glad you joined us.
Hugs
