For the pig sign would 12 years apart be compatible

Firstly, I do think that the age disparity does not count if there are real feelings between a man and a woman. So do not worry about the age. Anyway, apart from the age, it can be a very nice pair for two both with the pig signs. As they are both mild, they can always get along well with each other.
The only problem is that they may not calm down in face of the difficulties. So as long as they can overcome the problem, it can be better.
