New to this site, and scared

I'm glad I found this site. I have been married to my husband, who has ADHD, for over a year but we've been together almost 9 years. We have a 5 month old son. I'm really afraid that our marriage is going to end, and my son will come from a broken home. I've always known that DH has problems- we met in a PhD program, and even though he's very bright, it took him 8 years of struggle to finish. He has since struggled to keep jobs, and has lost some. He now works a full time job, but is having so much difficulty managing it. He ends up needing to work on weekends almost all the time. This has left me with almost all the childcare responsibilities (even though I myself work three 10 hour days). And sometimes when he's supposed to be working, I find him just watching tv or whatever. It makes me so angry I can't stand it. Our house is a complete disaster, and I work so hard to keep it manageable, but I can literally spend what little time in the day I have without my son cleaning and picking up, and when I wake up the next morning, DH has left dishes out, left wrappers open, dumped his clothes on the couch, etc etc. We live paycheck to paycheck and my husband refuses to help set a budget. Although when not stressed he's very sweet, he's almost always stressed now, and this turns him into an angry, sometimes mean person. He practically ignored the fact that I was pregnant all last year (although this was absolutely a planned pregnancy), and spent the first 2 months of our son's life ignoring him. I couldn't believe it- he loves kids and we have always known we wanted them. it's better now but not great. I feel like I cannot let my son grow up surrounded by this chaos, but I'm so torn because I also don't want him to grow up without a father. We are supposed to start therapy soon; we'll see if it happens. I am so heartbroken and feel so alone. I'm sorry this is such a ramble, but it feels good to get it out there....
