Bloody hell sorry for that.. whats she doing? Least he did the right thing in ringing you.. i may be wrong here i dont know your bf.. but what coke does to you mentally.. if someone is pissing you off no matter how bad, or you have had a bad day.. your brain will tell you to get some coke it will be ok… its your brain wanting it and its secretly using the bad thing thats pissing you off to go and get it. Thats why its a creepy drug… maybe now.. tell him he cant use his ex as an excuse to use, because if he never had coke.. he wouldnt use it in this situation.. he needs plan another route to take the next time he comes to this situation. Thats my opinion anyway. But i dont know his full ins and outs.
So what you said to him then? And what your going to do?
