Advice anyone?

Instructions

(This is abt a guy and I need help understanding what he means, so if your a guy stick around to help me out! Also stay if your a girl too!) SO I have been liking this one guy, lets call him Cooper, and I cant tell if he likes me back. My friend who has alot of classes with him always gave off hints I liked him (I was unaware of this at the time btw) so he would start liking me ig? Idk. Anyways, the only realationship I had with Cooper was that in language arts he would always steal my pencil and throw it in the trash and I would throw his away, we would tell eachother jokes all period long and such. So I start liking him after he plays a big role in a play I went to with my friend. Anyways, Cooper ends up finding out I like him, so my friend is like, well do you think shes cute? (Part im confuzzled abt) and he goes, “I guess”. So I wasn’t there when he found out, I didn’t even knew he knew till yesterday, so I dont have context one what his tone was, if he was smiling or blushing, IDK. So this year I have another class with him (this is the second day of school btw) and he keeps making eye contact with me and I cant tell if he looks annoyed or happy, he just kinda looks like nothing. But he has to make an effort to look at me, since im in the back of the class and hes in the front. Also on the first day of school I got off my bus and almost smacked right into him, and he looks at me, eminently looking away and blushing. So then that makes me wonder: Yall does he like me back? And what did he mean by “i guess” to me being cute? If your a guy, WHAT DOES THIS MEAN?! and if you a girl, I know you have advice! Now GIMME (Just to clarify cooper is not his real name!) GUYS MORE STUFF HAS HAPPENEDDDEED So Cooper got my number from my friend, we will call her emma. SO this is how it goes I talk to him, he tries to guess who I am since Emma gave it to him without saying who I was, and so yeah, he was guessing! Then he finally guessed But before and while he was, he was texting very friendly, with emojis, etc. And we was aswell once he found out, he responded very fast to my texts, funnily and we shared some inside jokes. When he had to go he told me exactly why and was like “byeee” which was kinda goofy, and when he found out it was me he was not acting awkward or anything and still funny SOOOOOOOOOOOOO? Infact he seemed like he enjoyed texting me! Guys my ex just texted and we have had no contact for 4 months saying he wants to be friends. But my friend (also his cousin) is telling me that he wants more contacts, but he was also begging for my number, but some of the reasons was because he wanted more contacts! He also said he needed to talk to me and rn I am so confused, also HE IS LIKE BEST FRIENDS WITH COOPER, but he hasn’t seemed mad at all I like cooper, like, he wants to be friends sooo, strange (Aug 17)
