Talking to an Introvert

Okay so I matched with a pretty cool guy on Tinder a while back. He had mentioned to me before we started talking that he’s an introvert. I told him I don’t mind at all, but there have been times where almost 4-5 days will pass before we ever talk to each other. Sometimes I feel like I’m being to intrusive or bothersome. I don’t want to lose him because I really do like him, I can’t really tell if he feels the same way though :/ Maybe I should just be more patient with him and give it time.
