Get back to her. Shag her and then two days later text her "I've met a rich model. And she's much better in bed than you are. Goodbye."
LOL. Actually, if I ever bump into her in town (unlikely, as I'm avoiding TK MAXX lol) I have the perfect end to the conversation:
"nie mam czasu na zimną, pustą blachare która rzadko daje dupe, ale zawsze ma czas na wyzywanie!"
