I dont know what to do. I just found a crack pipe in the apartment I share with my ex addict bf. He swears its not his and even says he will do a pee test to prove hes clean, and that is one of his ex dealer/friends. I'm losing my mind because last october i caught him drinking and doing coke behind my back whenever i had my kids for the weekend. (I stay elsewhere with them every other weekend) I took him back just before xmas because he started na and aa and was sober and clean and then this happens....
