You are attempting to judge how you would be in a hypothetical scenario, but even in your hypothetical scenario, several important, relevant factors are missing. It is most generalized.

In how ever many relationships where silent treatment is employed against one partner, the effects can be devastating and even cause trauma. Moreover, the trauma causes the abused partner to stay and possibly develop a trauma bond (which is an biological addiction to the cycle of abuse.)

Additionally, in some relationships where the silent treatment is used, people are already in love (of what ever degree,) forming a bond (to whatever degree) and so on.

It is not always so simple and/or easy to just "break up" with the abuser and start over with someone else.

Your post is dismissive of how damaging the silent treatment can be, its possible effects on the victim and more.
