Break Up & Divorce

Am I wrong here?

I promise my heart’s in the right place but I’ve always been brutally unapologetically blunt. I’m not a bitch, but I come off as one. Not changing that for anyone. Anyway here’s the situation:

I don’t understand my generation (millennials who are now in their 30’s and 40’s) and their fixation with living with their parents. Yeah I get it, times are tough, but come on grow the fuck up and live on your own. Start saving money, get a roommate (or a few) and do it! Stop complaining about how your nonprofit do gooder job doesn’t pay enough, leave it and get a real job (that pays better), and grow up. I graduated college with large debt from student loans in the height of the late 2000’s recession. I was kicked out of my parents house and told to get my own place at the end of freshman year. I did it. I saved, I hustled, I sacrificed luxuries to pay my rent, my bills and pay off my student loans and I live in NY, the most expensive city in the US. I did it while working retail and moving up. No help at all from my parents. They moved to Florida and I haven’t seen them in years. I only talk to them on holidays

My ex boyfriend on the other hand left the military during the recession and went three years with no job. He lived off of unemployment benefits and VA benefits and he lived with his mother. He’s now working nonprofit, still lives with his mother (but says he pays half the rent, the utility bills, helps with cooking, groceries and housework). To me it sounds like him and his mom are codependent on each other, because he says if he moves on his own, his mom gets thrown out on the street. And on top of that he has ADHD which means I have to be the fucking adult. Otherwise he’s great, but I couldn’t handle him living with his mom or his bs disorder (which I never believed was real. It’s fake). I broke up with him for that, he now thinks I’m a bitch and my best girlfriend (also adhd and codependent on family because she’s poor) agrees. Was I wrong?

Forgot to include this, but we’ve been dating for 10 months. When he told me he has ADHD, I disregarded it because like I said, I think it’s a fake, made up disorder used to justify laziness and lack of attention to detail. He told me on our first date he lives with his mother and I continued to date him because he had so much potential that I hoped he’d eventually grow up and start saving to live in his own place (not with roommates because that’s something you need to grow out of by 40).
