When I was younger, I admit that I was guilty of using a similar excuse. I was lying to her and myself, I was really just discontent with the relationship and was reaching out for any reason to get out of it. I'm not proud of it, but its six years in the past and I've since matured. Short answer? I believe its an excuse.

Sounds like he's unsure of the relationship. Or maybe he's unsure about himself and doesn't know how to make you happy? I would say just give him the time he needs and let him come to you when he's ready.. that is if you're willing to wait for him too.
