Whether you have a great relationship with your mom or things are a bit more strained, she probably continues to occasionally loom large in your adult life. But though her meddling, thoughtfulness, and the like can sometimes work to your favor (and, as she says, comes from a place of love), your relationship does have to change a bit as you grow older. Some of the things that she may have previously done on your behalf she just really shouldn't be doing anymore — and some she shouldn't have ever done. The creepy things your mother should never do aren't all age-dependent, but they're things that, regardless of if she ever did them with your blessing, need to stop ASAP.
As a fully-grown adult human, there are plenty of things that you're more than capable of doing on your own that your mother shouldn't feel the need to do for you. Additionally, there are things that just aren't OK for moms to do to their adult kids. There still need to be boundaries in your relationship, even though they might be a bit different than they were when you were growing up. Relationships change over time and so too should the things that you do for one another (as well as the things to which you subject each other).
