Yes, if you don’t ask now you may never know if she likes you or not.
A few years ago I had a crush on this person who I now think liked me back. Me and this person were friends but never told each other. We are still kind of friends but no where near as close. Maybe if one of would have said something back then we would not be where we are today. So if you don’t tell them now you might just end up drifting apart
