Flirting

He texted me, but didn't text back but snap chatted?

We "met" online and then it moved to texting. He mentioned he added me on snapchat too after getting my number. We texted until 2am the first night, he even asked when the last time I had a boyfriend was. (Side note: is this a good sign? What should I take away from this/how should I read it) The next day I downloaded snapchat and he snapped me right away. He later texts me, i text back he doesn't respond so I wait and then try again as im getting ready for bed when he snaps me. Today he texts me saying he's sorry he thought he texted back. Well... do I just snapchat him (even though I never usually use it i had to redownload it)? Is he interested? I mean he doesn't seem like the other boys asking for snaps right away one guy even admitted he was asking because he was hard. I've never done online dating so this is all new.
