You're being way too hard on Ganji, Desdinova. You won't necessarily develop oneitis. You explained yourself the way a ganji game should properly be enacted:
The experienced (and natural) Don Juan will NEXT a woman when he is no longer interested in her, or she flakes on him. He will reflect on the good times he had with the woman, but realize that she is no longer worth his time and move on. The woman will dwell on his ability to just forget about her. She doesn't want to be just forgotten!...When she re-appears, he has the option of dating/fvcking her again if he so desires.
If you truly NEXT someone, you don't give them a second chance. Even if they come back, they're out of the picture. Moreover, if you next someone, you
don't make a concerted attempt to ignore them because you don't care how they feel about you. You don't want them to miss you.
Ganji games should be approached with a mindset similar to nexting (a moderate degree of indifference toward success/failure). As long as you continue to spin plates and get on with your life, you shouldn't develop oneitis for the ganji girl. And then once her IL is back up (assuming you were successful), then you sweep in all at once and capitalize on her high IL.
If you next a girl, you shouldn't get back with her ever.
All this being said, I haven't had much success with ganji games myself. Imo, if a girl is flaky enough to warrant a ganji game, you're probably best off just nexting her and finding someone better.
