Your sister-in-law was amused to see how totally defeated you looked as the meaning of what she was telling you sank in. And she looked forward to telling you wife about how much this news was devastating you emotionally, even to the extent that you had trouble keeping yourself from sobbing -- because she knew how pleased your wife would be to hear about your emotional distress.
Of course -- this was far from the first time this kind of thing has happened. In fact, when you go out with your wife, you always know there is a reasonable chance she will be leaving with someone other than you and that you will be spending the night alone.

Experienced: I couldn’t help myself to think of him again when you fucked me at the same place 🙈
Love it when my wife texts her colleagues.
