Almost.
They both have positive energy. If their balance were nil, they could remain for ever. And that is what happens near a gravitational source, e.g. a black hole. If their existence is compensated by a source of negative energy, the balance might get to zero and so, they can stay. That is the essence of Hawking black hole radiation.
But if their balance is positive, then they must return their loan in a time that is short enough to satisfy Eisenberg indetermination principle about energy values. And they can do that only by disappearing soon after.
And that is why our Universe is long term stable. Its total energy, and therefore mass, is zero.

Agree
Virtual particles that are created are the result of a quantum fluctuation, but the energy of this fluctuation must be zero, so 1 particle has positive mass and the other has negative mass, so that if they annihilate the mass is zero. If one with negative mass is sucked into the black hole, it takes mass away from the black hole, and the positive particle becomes real instead of virtual basically. So every time when negative particle enters a black hole, energy is lost in the black hole, because negative energy particles annihilate with the positive energy. Positive particles that were outside the black hole during that time go away from the black hole, which is hawking's radiation.
