Ok Ya'll have probably hear a story like this a billion times but i need conseil that my Friends are not giving me

ok there is a guy who goes to my school he's a senior(i'm a fish) but he is always giving me hugs that last like two minutes if not longer and he gave my his veste one jour when i was cold(he also a dit he would give me a piece of his cœur, coeur to keep me warm!) it really seems like he likes me... the problem is i figured out that he has a gf so im really wondering what is going on here& i really need advice.
