Am I doing the right thing by ignoring him?

Sounds like he doesn't want to be in a relationship right now. When you feel that something is off (and 99.9% of the time, we're always right) and you start to ask those questions, I feel as though they feel even more crowded for whatever reason. Even though, all we want is an answer.. so as to decide what the next step will be. Not giving you straight answers and avoiding the questions is definitely a sign. If he was into the relationship, he would answer them to ure you. Second, the "if you're tired of us.." line is just an easy-out for him. That way he's putting it out there I guess so he doesn't have to do the dirty work. He's probably hoping you'll say you guys need space or want to break up so he doesn't have to be the one to do it, but he's obviously tired and not into it for whatever reason. Sometimes guys will be guys. And they like to try to come back once they realize you're completely over them, so be careful. His attempts are more than likely not sincere. I say drop him completely. No need trying to push something when it's not a mutual want between the two of you. Good riddance, and good luck!
