Is he lying or trying to be nice to me?

So I’ve been talking to this kid for us 11 months now and we’re trying to hang out and we try to talk a lot but we’re just “Busy “. I caught the vibe that he might be irritated or I just might be a little bit annoying I’m a very bubbly person by the way. So I asked him “hey can I ask a question it’s nothing bad” he said “sure” I said LOL I don’t know if it’s just me but I feel like our friendship is dying like we haven’t been talking that much” and he said “I’m good just been busy” So then I said “LOL I just feel like I’m a burden to you ha ha” and he said “nah relax.” I’m having trouble figuring out if he’s just trying to be nice to me or if he’s just trying to dismiss me. Any opinions or advice?
