Just two short lines, and the second one breaks off mid-thought. The speaker seems to be talking to someone who hasn't noticed their absence, or at least hasn't shown it. "Doesn't seem like you missed me" is a flat, tired kind of complaint, without anger or drama. It sounds like someone who has already done the disappointed math in their head.
Then comes "guess I ment that little," and the poem stops. The unfinished phrase can be read a few ways. Maybe the speaker is admitting they didn't matter much to the other person. Maybe they're saying the feeling was small on both sides. Judging by the trailing off, they may have simply run out of words, or lost the nerve to finish. The misspelling of "meant" adds to the feeling of a quick, unpolished message, like something typed and left unsent.
The mood is quiet, deflated, and a little bitter. It's the sting of realizing your feelings weren't matched, said in a low voice.
