Freshman Boy!!!

My friend Jake who's a freshman [im a sophomore] broke up with his girlfriend a few weeks ago (I haven't hung out with him for a month or two) and now he's like giving me really weird signs! like I think he wants to hook up or something lol I'm scared! I legit thought our relationship was so clear - I call him my little brother lol 😩😩😩 and I think of him as a little brother too. How do I handle this?? Don't wanna lose him as a friend :(
