Does he like me or not? 10 points*?

Sounds like he likes you! Ok now about the Taylor swift thingy. It could be his fav or it could be a lie. He could also be trying to get things in common with you. I've done that before. I once lied and told a guy that my fav color was red too just so I could have that incommon. But it sounds like he does like you and you should try to talk to him about it. Good luck!
