I think a lot of people might call my BF a mama’s boy, while she doesn’t do everything for him to this extent, she would if she could/he let her (I’m very lucky that my BF, like myself, is really into their home environment so is clean and tidy). They have a really lovely relationship and he’s so sweet and gentle. Whenever my own mum comes over she tries to do my laundry, clean my kitchen, same with my other siblings. I really think that if there are major issues, this wouldn’t necessarily be the underlying cause or red flag. It’s probably wise to get a little more insight to their relationship? It took me a while to get used to my BF’s mum spoiling us, I couldn’t take the guilt/feeling that she thought she had to do such things etc but in the end my boyfriend was like ‘you have to trust that I know my mum, trust the relationship I have with her’ so I just let go and it’s caused us no issues and he’s a completely functional 31 y.o!
