To me, these lyrics mean:
She reached out to meet him and couldn't believe how well he was doing without her. But he says that when he really needed her, she wasn't there. Such a sad disconnect. They both want each other and they both feel the other isn't there for them. From the very beginning they were just too far apart, as if they were separated by time or circumstance or perhaps miscommunication. He doesn't feel he could be any closer to her, at this time, because of the circumstances and the time issues, but he wants to give her some time. And I feel that she obviously wants to give him the chance because she came out of her circumstances to meet him and see how he was doing. If she didn't care, she wouldn't make such effort to check on him.
