Im in the same situation. I think its a powerful method because you dnt want to let that person down, and its like someone else is in control of your urges, for once. I always get the 'why did I start this?' all the time, but thats just part of the addiction speaking I think. It blinds us.
It doesnt matter if you do it for someone else, because I think in time, when It does get easier, youll find you agreed for yourself
