Hey guys, Give some advice please. I really need it

So...I was really doubting myself of this guy. I don't know if I'm in love or just crushing him, and also he is my first ever crush in real life bc my life are for ANIMES.
Soo Everytime I chat with him make me happy and like I can't breathe well and my heart is thumping hard but it's not fast. I think of him sometimes and that's so really cliche. I really don't know what or how will I fo to myself. Even tho I read so many shoujo manga or anime. I just need someone to give me an advice (●´⌓`●)
