I've known this girl for about 4 years now and we'll both be sophmores this year. The problem is that I've started developing a crush on her. This feeling has just been growing more over the summer, to the point where I feel my heart race when saying something as simple as happy birthday to her. I really like this girl but I really don't want to make things akward between us. Should I try asking her out, hope these feeling pass quickly, or if any of you have other advice it would be much appreciated.
