I'm not so much asking what I should do, but would I be able to rush at a different school in the fall if I rush this semester, but decide to drop my pledge before initiation? I don't want to know whether I should transfer, but whether or not it would be a smart idea to go through recruitment.
You can rush again only if you don't get initiated but if you drop where you are, you may have taken the spot of someone who probably wanted to rush there and stay.
