One step forward, two steps back. That's the way it usually goes until you get the hang of things. Don't discuss your situation with your mother in law. Blood is thicker than water and she'll always take her baby boy's side, even if he lies, cheats or steals.
As for his foot, that's up to you if you want to wait on him and feel sorry for him.
As Scarlett said "tomorrow's another day".
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
