Young kids and a husband in denial

Hey all I'm new to this site but so glad I found it. My son is ten months old and as we've gotten more responsibilities my husbands adhd has become more of an issue. He was recently diagnosed but states he is taking his meds when I know he isn't. My husband has no idea how much I think about separation because I can't communicate with him. He either blames me for pretty much everything, states I just want to change him or he doesn't talk or respond at all. I'm so lost lonely and confused. I don't know if it's better to try and stick it out see if he'll change and start understanding how impactful his untreated adhd is to our family or leave now before my son starts to see everything I do and before it impacts him. My husband is an asshole when he drinks socially but yet refuses to give it up, he does t handle his emotions well gets angry easily so I'm always walking on eggshells, he never finishes projects around the house (we started our deck in June and it still isn't done). I just don't know where to go or what to do anymore ... my parents and friends have also noticed he is always on his phone isn't interacting, is distracted doesn't respond to questions when asked the first time. isn't getting anything at the house done and I can't hide my frustration anymore!
