Relationship Advice

.I recently broke up with someone who I was in a long term relationship with. Although this person was the love of my life, he was a binge drinker. After three years of trying to help him stay sober,(it never worked) I asked him to leave.I know Im doing the right thing in ending the relationship,it’s the best thing for me and my kids (11&13)but it’s so hard cause I still love him. I have no intentions of getting back together with him, but remaining friends with him is something I would like to do but don’t think I can because of the strong feelings that are still there. I need to make a clean break.I am an extreemly strong person but this has been very hard for me. This man really had nothing in his life except for me and my children, and now that we have had enough, I know that he will go down hill from now on. I realize he is a grown man and that I am not responsible for him or his drinking, but it’s going to be the hardest thing to do to watch him drink himself to death and not do anything for him.I need some advice please.
