SAHM probs? Or am I dramatic?

I’m feeling very alone on this and maybe crazy for feeling this way. I have a husband that is never home. He owns a landscape business and he claims that’s why he’s never home. I’m accused of cheating constantly when I’m home all day with our three kids and one on the way. I’m home cleaning, cooking, caring and love our kids while he’s gone from 6-7am until 8pm- 12am it’s different all the time. When he gets home 90 percent of the time he’s sitting on his phone and ignores the kids and I unless I nag him to get his attention for myself or the little ones. He will once in a great while cook something or clean something if I ask. I have a 4 year old, 2 year old and 10 month old at home. I wake up with our baby every night, he never does, ever. I’m drained, I’m beat from asking for his time and not to be treated this way. To him I’m the wife and this is what I do take care of the kids and everything here because he worked for us all day he says and he thinks I want to be “poor” he says. 2019 he kept me home same times I stated above but actually sometimes it was even later than that claiming he was at work but really wasn’t, he was drinking and doing drugs during the day. Would have his works drive around with him and just had the time of his life. Sometimes I didn’t see him until super late like the next day morning time like 2am-6am. When he wants to be intimate most of the time I am not wanting to be I’m drained and just not into it because of how I feel towards him. Am I crazy? Am I asking too much from him? Am I bad wife? Am I lazy? Do I need to step it up and just stop feeling this way?
