you are free to do whatever you want, but I am going where I want or have to go (may be used as a pretext for breaking away from a group)

you can do what you want (like), but I must be off (going).

«Ну, ребята, кто куда, а я в сберкассу, - надо в деревню сходить». - «Прощальный визит - пошли!» (Гроссман 2). "Well, my friends, you can do as you please, but I'm off to the village." "A parting visit? Let's go then!" (2a).

Valentin Kataev, in The Grass of Oblivion («Трава забвенья»), 1967, attributes this phrase to the poet Vasily Lebedev-Kumach.
