tied to (one's) apron strings
Controlled or dominated by one. Used especially in reference to a man controlled by a woman. I'm worried that my husband will forever be tied to his mother's apron strings—he's a grown man but still does every little thing she asks! Can you make a decision on your own, or are you tied to her apron strings?
tied to someone's apron strings
too much under the influence and control of someone (especially used to suggest that a man is too much influenced by his mother).
