What's the truth about antigravity?

I had a manager who believed that since magnetism is a dipole, that we should also have positive and negative gravity.  The problem with this idea is that it is likely a bad analogy.  I have seen videos stating that gravity is not a force, but a by-product of moving through curved spacetime.  (I am still skeptical of the "spacetime" concept, thinking of it only as a useful and accurate model.)

Anti-matter is simply matter that has an opposite charge.  There is no reason to think that it would be affected in a different way by gravity.  If it were, I think that we would have to rewrite the laws of physics.
