A speaker is trying to move on from someone, but not quickly. The opening lines, "Taking things / slowly / hesitantly," are broken up so that each word gets its own beat, almost like small, careful steps. That slow pacing is the whole approach: the speaker is protecting themselves.
The reason comes in the next lines. They "don't want to hurt / the way I have been," which suggests that the pain has been real and recent enough to still sting. Moving on too fast might mean getting hurt again.
The ending is the most honest part. The speaker admits that they would like to say they're over this person, but they can't: "I'm not fully over you yet." The word "yet" matters, because it leaves a little hope that things will change in time. The mood is quiet, vulnerable, and tender, with no drama, just someone being truthful with themselves about where they are.
