Is my boyfriend too close to his mom?

My boyfriend is a little older than me. His parents are divorced a long time but his dad is not alive anymore for years.

He and his mom own a multi family home. They rent one apartment. He has another apartment. And she has the third.

It saves him money and one day the house will be his. However it is starting to annoy me that his mom is so close. When I stay over on the weekends we always have to go to her for a meal and see her. He also goes to see her at least once a day. I feel like he may as well just live with her. Sometimes he will go to talk to her while I am in his place and leave me in his apartment for a little bit (less than an hour) She likes me but I am concerned about whether he lacks independence? He works and brings in the majority of money and has a good salary.

His mom lives with one of the other brothers so she's not alone. It's not that I don't want them to have a relationship I just worry more like if we were married is he going to get his mom in the middle? Run to her to avoid me? Those are normal concerns. My dad was overly attached to his mom and listened to her but not my mom

Also because he makes a good salary and she doesn't make much, nor does his brother, he is supporting them financially. His mom does work but she doesn't make a lot of money. So the house is really his but I'm sure his money would keep going to them even if we married...
