Two places that I didn’t understand

1. In the middle of the film, why did the male pig's feet let the female pig's feet give Shannon (the old black man) a box of money, and the old black man said to the female pig's feet: My wife she's... Who is his wife? What does it have to do with this matter? I don't know if the movie didn't explain it or I missed it.

2. The film finally proves that the male pig's feet is not insane, he can indeed travel back in the past. That also means that the actor did cross back to save Belinda (the male pig's ex-girlfriend). Then why doesn't the actor remember that he has crossed it? Have you saved your ex-girlfriend? Why continue to travel back to save the ex-girlfriend?
