Alcoholic SO

Ashley • TTC baby #1 with my fiance since 7/2015. Fighting depression for 5 years. Wish me luck...
My SO is and always will be an alcoholic. We've tried everything from detox (professionally and at home), rehab, cutting back to only weekends and so on. Nothing has worked. I need encouragement at this point. Someone to tell me that they've made it through this struggle. His fight is my fight. But I'm at my breaking point. I want kids, and so does he. We have everything we could have ever asked for, house, vehicles, jobs. Basically the means to raise a child. But I won't have one under these circumstances. What can I do at this point?
