Boys are confusing

I started liking this boy 2 years ago, when I was a freshman and he was a junior but last year he got into a pretty serious relationship. They broke up this past march and he started snapchatting me and ocasionally texting me about 3 weeks ago and it has been nonstop ever since. However, he has not asked me to hangout! I don't know what to about it because I feel like I was given a second chance with him, but if he was interested wouldn't he have asked by now? If anyone has advice I NEED IT!
