How do you understand this guy?

I met him at friends place last year. We have a lot in common…so We kept in touch. He seems a bit shy/not confident un himself.

I proposed him to meet in a casual way both of us several times but he always found an excuse not to come..
A few weeks after he invited me to join to some friends party. I couldnt join but he insisted a bit. He invited another time but I had already a plan and he did everything to push me to cancel it and join him. lol I didn't cancel…
Lately We met again at the same friends Place And the connection was awesome. Then We kept messaging each other every day, even from work.
He sends me messages also early in the morning and before to sleep..
So today I proposed him to meet for a drink at the market (casual Sunday) but he said he was just waking up and that he feels lazy….. and that after he has his football meet.

Ok. So How should I understand his behavior…? Is he afraid to stay alone with me?
