He will stare at you. I repeat, HE WILL STARE AT YOU. Literally every single relationship I’ve been in has started with a boy staring at me.If he has your number, he will randomly text you just to see how you're doing.his pupils will dilate while speaking to you. This is a scientifically proven fact. I tested it and it’s true.The first thing he’ll look for in every situation is you. Watch him when he walks in the room. If he stops looking around when he finds you, then chances are, he likes you.He will smile when you smile, even if he’s all the way across the room and just happened to notice. Guys love girls' smiles so when he sees you smile he most likely will too.This seems really obvious, but pay attention to how he treats other girls, if he treats you differently, then he probably likes you.He will be extra interested in the other boys you talk to. He may ask if you're friends, or how long you’ve known them, or simply just comment on them.He will slow his walking pace to match yours. This is just another scientific fact that I tested, and it works.Don’t make a big deal out of this one because most guys do it anyway, but he may sit with his legs apart often because it makes him appear more manly. No explanation needed.When he talks to you he will tilt his head slightly. I don’t know why guys do this but when ever a guy is actually paying attention to what you're saying, he tilts his head.Even though he will listen to what you have to say, he will also talk about himself A LOT. He wants to show you all his accomplishments to prove he’s worthy of you.He will remember a lot of the tiny details you randomly throw into conversations sometimes. For example, my bf somehow remembered that I hate orange flavored dark chocolate lol.This one is only true for like 80% of guys, but he will often fix his appearance when he’s with you.(Touching/fixing hair, ajusting clothing, actually bothering to tie shoes).If you ask him who he likes, and he replies asking you who YOU like, then there’s a pretty good chance he likes you, unless he’s someone who struggles with trust.He will give into the things you want to do. Like instead of watching football( lots of guys find this very important I really don’t know why), he’ll decide to go to a concert with you or something. Or it could be super low key, like instead of playing soccer, he’ll play volleyball with you or something.This goes along with #15, but he will not be able to say no to you 99% of the time , like my bf did NOT want to join choir, and yet I asked him to join, and he said he would try it.He will use a wider variety of facial expressions with you than he does with other people. I don’t even know why this is, it just is.Repetitive lip action. If he’s biting or licking his lips a lot when he’s around you, there’s a chance that he’s thinking about ahhh• doing other things with you other than talking.
