Picture a day about 5-10 years down the road, when she runs into you somewhere, randomly. Then think hard about exactly which traits you would need to own (at that future point), which would cause her to walk away mortally wounded and immediately seek out the nearest tall building to commit suicide from. Who is the future 'you' that, after one casual conversation, she would walk away chilled to her bones from unrelenting depression, knowing she just came face to face with the biggest mistake she's ever made?
Become THAT guy, starting right now. In about 6 months she will no doubt be inconsequential to you, but you'll have stepped up your game and developed some pretty f**k cool habits.
Otherwise just eat a shitload of greasy food, drink a lot of Grey Goose, and bang a metric ton of sluts.
Basically, like Charai and Prof are suggesting... beat her at life.
