She Felt It Coming
We feel that the sorry sender of these sad texts somehow knew what was about to happen. Sure, they wanted the exact opposite to come about, but in a sense, they felt like they just already walked straight into it.
Perhaps all these people that were telling them their relationship was about to end, knew more than they were letting on. It sounded like this union was doomed well before this text exchange took place, and this is just confirming what was already a done deal. Kthxbye, as the kids say.
