You are over the moon
If I would have known better, I’d say you are head over heels in love with this person. You love their company and would do anything just to see them and be with them. Some people might call it an obsession.
You go out of your way to please this person all the time. You practically live for this relationship. You might want to tone it down a notch so that you don’t appear too clingy. However, if this crush of yours is as high on you as you are on them, then go for it.
You are in a loving and healthy relationship
