Is it normal to think about a girl all the time?
Mostly.Normal for most people
Yes, it’s normal to think about someone a lot when you have a crush or strong feelings. If it’s crowding out sleep, responsibilities, or your ability to enjoy other things, it may help to deliberately give your attention some breathing room.
When you’re excited about someone, your brain can replay conversations, imagine what might happen, and generally make them the star of the show. Lots of people go through this, especially with a new crush or when the feelings are uncertain.
It’s usually harmless, even if it feels a little ridiculous. If the thoughts are getting in the way of your day, try focusing on plans, hobbies, and other people too—and remember that having intense feelings doesn’t mean you have to act on every impulse.
