Accurate. But addiction metaphor or no, it obviously was MATT who was trying to quit this time. And Foggy was taking actions to support the fact that Matt was the one trying to quit.

Everything he was trying to do was based on the mixed signals he was getting from Matt (and really, has always gotten from Matt) about what Matt wanted from him and how he could support him.

And sorry, but you don't owe any friend a willingness to stand by life choices you think are dangerous or going to get them killed anyway. Especially when those life choices could also fuck up your own life peripherally in pretty epic ways.
