Ok Ya'll have probably hear a story like this a billion times but i need 建议 that my 老友记 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 分钟 if not longer and he gave my his 夹克 one 日 when i was cold(he also 说 he would give me a piece of his 心 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.
