You don't need to read into it. It boils down to something pretty simple: if he was done with you, he wouldn't be talking to you again, especially about trivial things. He's not done with you.
It's up to you if you want to give it another shot. Usually after a break up, if there is ever a chance, there's likely only one. Do you think he is ready to hold up his end of the bargain? Do you think there has been enough time passed and he's been enough on his own to really change? If not, I'd take it easy with him and not try to rush back into anything.
You have lots going on in your life. Do you want to try something with your online date? Maybe you should focus on that.
Which brings me to another question: has anybody ever wanted to go back to exes, and if so, why?
Waking up next to a beautiful girl,
Step outside and say hello to my beautiful world.
