Has anyone ever been with a "mamas boy"

I always thought grown ass men were supposed to grow out of this...

I've been so annoyed lately with just the THOUGHT of how much of our buisness my boyfriend tells his mother. Although I KNOW and respect their relationship. I find myself refraining from telling him certain things and he's my best friends. I always have told him everything. The main problem I have with it is, She tells everyone everybody's buisness. I'm the opposite. I keep my life to me. She is always on the phone with a friend or family member talking about someone else, and what she heard ect...

She calls my 31 year old boyfriend her "umbilical boy" 🙄🙄🙄 and will sit there in front of everyone including family and friends and brag about how my bf is attached to her ect... I kinda get embarassed... I'm pretty positive he does too. He will just change the subject or out his head down. He always tries to quickly brush her off. He is her only son, and since her husband has a "bad neck" he does everything for her. Which certain things I completely understand like cutting her wood every few months to put in her wood burner, I even help her with that as much as I can, But other things like she will literally call him to come help her move furniture when he lives 25 mins away, or to help her carry something to the garage, shes in great shape and health, Just stupid things. She is constantly bringing up the past and how she always was there to save his ass as a teenager when he would get in trouble, like the same stories over and over.... 🤷🤷🤷 Which I just listen and smile. Idk what else to say. She has 2 daughters too and she literally could give a shit less about either one of them. She will straight up say that. She says all I need is my boy.... Well its been 3 years and we have a baby now and this is getting on my nerves, not so much how needy she is but the part where he choses to vent to her and his dad. His dad I don't really care too much about cause he ain't gonna run to the phone and call everyone including my boyfriend's ex girlfriends, and tell them. Yes! She talks to his ex girlfriend. 🙄🤦 I have expressed how much I hate this to my boyfriend, But I am just worried that he will become more private with it. I just think this is the way it's always been. His mom has a way of manipulating him into thinking he needs her when in reality it is the other way around. His mom even gets deeply involved in his relationships and when his friends would come over she would try hanging out with all of them... She's just extremely weird. Idk maybe I've never dated the typical "mamas boy" prior to our relationship. Anyone else have any problem like this? He can continue to do whatever he wants for her, I never complain. I just don't want her to know everything and every little dispute we ever have in our relationship. It makes me look at him a little differently. Like he's not an adult. Like he can't do or handle anything on his own... I think now everything is just getting annoying about her because im irritated and I'm nitpicking about things I usually wouldn't.
