I dont know, i also assumed there was a connotation of infidelity, although i agree with both what both wtfyourface and tied2amelody said, i feel like her not being a big enough person accounts for the "i could never do the same" part but still doesnt explain the "she doesn't know i know about it" part. i think there still is some hint of infidelity in that part or at least another angle to the situation
