I think as long as you are working on yourself before working on the R/M- that is the correct line of attack.
I always thought- problems in my R/M: -lack of intimacy -lack of connection -lack of quality time
So like a moron, I try to correct those issues. Problem is my W had lost respect for me- so I would have to fix myself before I could address those problems.
If you're having a hard time w/ smoking- now might not be the time, so consult your doctor...but chantix is a great way to quit.
Ironically, I had not smoked for nearly a year then picked up a month after the bomb.
