I think the fact that your still on contact occasionally is pulling up feelings based on a sense of loss which lingers after a break-up, and this might be stopping you from fully moving on.
However, if you feel it's wise, when you next text her, ask her how she feels.
Still, it sounds like she might be someone who wouldn't mind having the best of both i.e. being with you when you wants but no having to commit?
