i spent 2 and a half years with one girl. high school age, I assume? you can relate. she broke up with me for drinkin and drugs, then almost immediately after that, she began drinking and doing drugs, girl became a crack potato no less, really a crack potato. My response.....
Rat the dealer, and called the police, revenge can be had, but do it legally
And find a new one,a girl, many to be had, believe me, i happen to like English accents, move the hell on. things be ok
