Boyfriend's relationship with his Mother?

So my boyfriend and I have been together for about two years.. we are both 23 years old. He lives with his mother and I stay over here with him quit a lot. I just want to know if the relationship he has with his mother is abnormal and how I should handle it.

He is a deep sleeper and sometimes has a hard time getting up in the morning.. but he asks her to make sure he gets up in the morning for work.. even though I am with him. so she calls down the hallway his name until he gets up. She is always babying him and asking him if he has eaten anything and reminding him to make sure to bring his jacket to work and so on..he broke his arm awhile back and she was continuously asking him how it was doing.. going to the doctor with him..things like that. She does his laundry when I am not around too. Makes him lunch for his work break.. Also she buys him whatever he asks for and totally spoils him. She does not want him to have any student debt so she is going to pay for his entire college tuition, she bought his car, phone bill and he does not pay her rent either.

It is just making it really difficult to view him as a man when she treats him like a helpless child. and some of the things she does seems like my role now.

She is polite towards me and has never acted jealous or rude towards me or anything like that. Helpful advice would be appreciated.. please no rude comments or criticism.
