sounds like you wrote about my situation. my husband dabbled with pain killers for years then about two years ago it got out of control. i wish i could give you some real advice. we also have a son (he'll be two this month) and he's my biggest reason for staying with my husband and wanting him to get better time and time again. right now he has been clean for about two months but i always secretly am scrutinizing him to see if he's getting back into old habits. ive always threatened leaving too...that always makes the situation worse. not with his pills, but with our relationship. while on the pills he becomes a different, mean, inconsiderate person that says horrible, unspeakable things sometimes...so saying that i want a divorce or that he's a bad influence on our son, etc always made things 10 times worse. i'd confront him while he's very relaxed and your son isn't around if possible (in case that would make him more tense about the situation or it turns into a fight, that way your little guy wont have to deal with the argument too). tell him you realize he's had a problem and you're just concerned about him because he seems to be falling into some old habits. i'd just try to stay really calm, rational and nice...just seem totally concerned but not throwing in accusations, etc. (which i know is really hard to do). then it will depend on him. either he'll be like my hubby normally was and get really defensive or he'll get how my hubby was last time and break down and vent. it took so many tries for me to get through to him. and countless threats of leaving. i told him the last time was his last shot. he got off the pills and knows that its his last try since our son is at the point where he sees the differences in his father. i know this isn't a ton of help, but just know you're not alone in this situation. also, if he's been in treatment before and you really think he's using do they do interventions where someone comes to your house and talks to him? sometimes they're more willing to cooperate and not lie then. or maybe he should still be going to some of the outpatient support groups. hope this helps a little. .....and good luck to you, your husband and your son.
