What will a woman think of a man who is in his 40s but lives with his mother?

He is 40, lives with his mother (it’s her house) but she’s been in and out of the hospital lately. She is ok, feeling better and back working now. But he has never lived on his own unless he was in a relationship and the woman was the primary provider, and he never works and doesn’t have a job. I called him this morning and asked him what he was doing and he said he was getting dressed and taking his mom to the doctor, even though she drives herself to work and everywhere she wants to go. So I said “she can’t drive herself to the doctor” and he got mad and hung up. He is always talking about his mom, every conversation we have he mentions her. If I want to come over, he says he’ll ask his mom. She is in perfect condition now, she just has health issues here and there. He is always asking for money but I'm only 18 and sometimes he is overly nice to get that I feel. Whenever he isn’t able to do something because of finances, he blames everyone else and says that people leave him “broke”. 

Just a few days ago he complained about gas on his 2005 Mercedes’ and said he wasn’t going to be able to pick me up because gas is too high where he lives so I asked him why did he get the car if it takes so much gas (91 premium) and he said it’s because he wants to drive “comfortable and luxurious”. I told him the way I was raised, my mom told me you're supposed to get a car that gets you moving and something affordable and he said "that's not the right way to live that's if you wanna be cheap and you're broke then I guess."

I don’t have a problem with him being there for his mom but the Clinginess is starting to bother me.
