Looking for some insight here...

So, I started seeing a guy. We talked for a while, I was over his place, he was over mine, we spent some time together, I really like him and like where its going. Well, he had something happen to him that was very personal and he needed some time to himself. Thats all fine and dandy, but the responses from him became so quiet and I understand. In a way I feel very selfish because I want to just talk to him and make sure he's okay, and just pick up where we left off but obviously, I need to give him his space to regroup and feel okay. I can do that, but it is driving me insane. Well, we are still single. I'm single, he's single, it's fine. We aren't tied to one another. What bothers me is that I checked Grindr (anonymously) and saw he was on it, online, near me. I know he has a friend that lives near me, because he wouldn't have come up if he wasn't there. I know he goes there to hang out with friends, that isn't the issue. Fine, do your thing. No big deal. What's bothering me is that he's still using grindr, STILL online (the light was green) but he has BARELY talked to me. Should I feel slighted by this? Or am I just crazy?
