I need help please...?

Me n my best guyfriend have been "talking" for awhile.at first i would get giddy and school girly just from a thought lol. well i figured i was just infatuated. he moved but only temporarily n we never stopped "talking" but while he was gone some things happened (on his part) that kinda jerked my head outta the clouds. But we still really like each other n r more than likely about to date soon. the giggly me went away when he messed up but i still like him im not "infatuated" with him anymore. but i realized even tho he screwed up i still like him and got over it n now i just get erfly's when hes around and its just the two of us. i see the relationship with my heart AND head now no more head in the clouds.question is the fact that he did mess up n i was hurt but moved ped it, want to spent as much time as i can with him as we can, and just feel so happy and right with him.. could i be falling IN love with him? i know i love him but never been IN love b4 so idk.
