I know how you are feeling i am sitting ion the same postiton as you at the moment, my partner is addicted to heroin and after many attmepts to get him off the stuff i realalised that i could not win. We were always put second best and for that i am angry, i had to put him out last week as i was at my wits end with it all, everyine here is great and very very supportive, you have to focus on you and your kids just now, it is true though he will not take this easy nor did mine but you have to be strong and stick to your gns, it is no life for the partner of an addict as your left with all the mess to deal with and upset. let him deal with the consequences of his actions once and for all and let him hit rock bottom, your not doing yourself or him any good if you keep catching him before he gets there. YOu have to stay strong now and live a healthy life without all the stress and worry that he brings into it. xx goog luck and just remeber your not alone xx
