Am I obliged or at least in practice, if I want to get along with him,
stuck paying so much for part of the fence replacement with my
neighbor. I was prepared to pay 1/2 of 1/3 which I thought might be
30 or 40 dollars, but he says half of the one part we share is $125.

Who owns the fence? Was the original a shared cost? If so, you may have
some obligation, if not you should have no obligation. If you don't want the
fence and do not share ownership, you should not have to pay anything.
