The truth… get rid of them all. You need non using friends. Its plane and simple, if you dont want to use, cut everything off regarding coke, even family members.
Whats more important, keep your mates and maybe relapse then back to a vicious circle.. or that £600 being spent on your kids. In life we have to make sacrifices and no matter what our kids should always come 1st. I know its hard im struggling myself with coke. Not as much as you, but im still an addict and it upsets me when it can be going on my kids aswell.
Were do you think you will be if your gf and kids left? I know what would happen to me.. id be in a flat… getting wrecked every weekend and lead astray. Im so glad my gf has stood by me.
Your right though, delete everything you have to do with coke
