If a guy doesn’t deny liking you, then he likes you, right?

I’m in a group chat with this guy who I think likes me, and there was speculation going around saying that he had a crush on me. Anyway, this was all happening in the group chat, and he never denied not liking me. I’m kind of sure that he’s interested, but I’m still confused by his actions. He’s bought me food (wasn’t a date), given me flowers, and is always doing favors for me. BUT, I’ve invited him to hangout with me twice, (and other people) and he couldn’t make it both times (he had valid reasons for not being able to hangout)
