Dealing with a Momma's boy

I started dating a really amazing guy the only thing wrong with him he's the biggest mommas boy I ever knew. He's 28 years old his mom will come over to his house and clean it do his laundry and will cook for him I was over at his house last night and she just shows up doesn't call before or anything I told him and he said it's nice to have someone take care of him, I told him that I thought it was weird and he just said that it's not and to deal with it and He really likes me a lot and he doesn't want to lose me over this. His gfs in the past broke up with because of his relationship with his mom. I want to be okay with it I'm very close with my family I really like him and want to make it work not sure what to do, do you have any advice?
