What does all this mean?

There's this guy I've really liked since the start of the school year, but up until two and a half weeks ago, he had a girlfriend (she and I were Friends as kids, but popularity got in the way in middle school). It's not clear who broke up with whom, but I think he broke up with her. She's telling everybody that she dumped him and he's "so heartbroken", but she also clings to him, flirts with him, and he doesn't do it back. If anything, he's annoyed with her (yay!) However, he hasn't changed his FB status. Hers no longer says in a relationship, but his does. Of course, her name isn't attached anymore. It's possible that he just hasn't gotten to it (he hardly goes on, and when he does, it's not for long), but he has been on at least once since then. For months before the breakup, I debated if he liked me back, even a little. He looks at me all the time, always has his body pointed towards me, brushes me intentionally as we pass each other, blushes occasionally, etc. Before the breakup, he'd always look away when I caught him staring o refuse to hold my gaze when he caught me. Since then, though, we've held eye-contact for 5+ secondi multiple times, and everything I mentioned above escalated. There are still times he looks away, but he's letting me catch him più and more. A couple times at lunch, he'll be sitting with his friends, and as I pass, he'll turn his whole upper body towards me, making it clear he's looking. Also, he didn't accept my FB friend request until two days before the breakup. It pended for months. His ex is jealous and glared at me (still does) all the time when they were together. Maybe it wasn't a coincidence? Still, he hasn't made a sposta at all yet. I get that he just got out of a breakup, but wouldn't something have happened da now? Here's a downer. When we make the 5-10 secondo eye contact, I always smile a little. He usually doesn't. Maybe it's just his way of reacting. He is pretty stoic. I don't know. All these good signs, then that bad one
