Is it normal to have a crush on your grandma?
Unusual.Less common, but harmless
It’s not a common crush, but having an unexpected feeling doesn’t make you a bad person. Keep clear family boundaries and don’t act on it romantically or sexually.
People sometimes use “crush” to describe a mix of affection, admiration, comfort, or attraction, and feelings can be surprising. A romantic or sexual crush on a grandparent is uncommon, but the feeling alone doesn’t define you or mean you have to do anything about it.
Treat her as family and keep the relationship appropriate. If the feeling is upsetting, persistent, or getting in the way of your relationship with her, talking it through with someone you trust may help.
