If she ain't ready for a real relationship yet, then she ain't ready. Further, she may never be ready. My advice is to keep her as a friend, but expand your circle and date a few other women for a while. If something gels, fine, but in the meantime you're at least out of the house / job rather than moping around. I know quite a few people who didn't find their 'true loves' (if you'll pardon that hackneyed term) until they were in their 40s, so don't let the 'ticking of the time clock' make you rush to try and find someone.
