How can I tell if I’m enabling my spouse? Pt 2

Hi, in addition to my question I recently posted, I think it would be wise to add that my spouse is an addict. When I try to reason with him it feels like I’m working with an addict, not my spouse that I have known for the past 12 years (even though he has been an addict since his adolescence, so not sure why I am separating the two).

Through this process I have been finding ways to be fulfilled on my own regardless of his actions, but I worry that this mindset is making me become somewhat apathetic to the idea of marriage. I also worry that if I continue to get to a healthy mindset regardless of his actions, I’ll get to a point where I’m so independent that I wonder what’s the point of being in a relationship where there isn’t any bilateral accountability? Thank you!
