situationship or not?

i feel like me (16F) and this guy (18M) are in a situationship but i don't know what to do.

we see eachother almost everyday at the library and study together, and i've been picked up and dropped off once by his dad, and our mums are friends.

he's been to my house twice now and met my whole family.

and he always stays really late like last time he stayed until 1:30am and this time he stayed until 3:30 almost 4 and we cooked dinner together and stuff too

and we call a lot (but its always me who initiates the calls) like for a long time too like we've called for 4+ hours and stuff like that.

but once on call he like mentioned that he found another girl 'interesting' and like yeah idk

he's also given me his coat, swapped coats with me when i was wearing a vest and i was FREEZING and i js happened to bump into him.

he's also given me his hoodie..>< but we're just friends right!??

help me out here pls im going crazyyyy
