Boyfriend problems, just really confused.?

ok so my bf wanted to dump me cause i was getting mad at him over small things, which i wont doubt ive done that. and instead we talked things out a little and he decided to give me a second chance. and ever since then that day hasnt been brought up, it ws lst mon, but now i feel like things are weird between us. like one arm hugs and idk, lke tomorrow were gonna talk and he seemed fine bt a little annoyed about it. and im jst wondering how to tell if someones still interested, lke we havent had so its not lke he would be getting that out of the deal, so im kinda confused as to why i got a second chance, when he seems a little offish. and tomorrows gonna be the first time we actually really talk about what happened.
