Dating a mommas boy 😲

Ugh I seem to attract them.my current boyfriend is a mommas boy and I'm starting to get sick of it. I feel like we can't spend anytime together without her pestering or calling asking him to do things for her and this and that. Tonight we were watching a movie and I had to leave early( this is only bothering me becuase I'll be out of town working for a week this was the last time I'd see him.) He's almost 24 and is getting his Masters degree and I feel like the relationship with his mother is the only thing that isn't healthy. we went swimming today and his mom made him take a shower after. she just bosses him around like non other and it irks me. He doesn't deserve to be told and demanded what to do. I know he loves her but she'll make him go shopping and do all these household chores on her dime. I understand that he lives with her while he's finishing his program but she doesn't have the respect to wait. For instance if he says he's busy with homework or stocks she'll tell him you need to do it NOW. She's very strong willed and it's stating to make me turned off towards him. If I were to tell him things then I know it would cause an argument or misunderstandings so I don't know how to approach that it's unhealthy... any advice 😳
