How much did Pats mom manipulate in silver linings playbook?

I know it’s a random and niche question. Spoiler alert how many years later? Anyway saw the movie this weekend and at least one part his mom is shown to have manipulated things. But for anyone who saw the movie and remembers it how involved was she?

Yup I agree his mom loves him and she needed to give him a project. I also think she’s the mastermind to this movie as it deals with mental issues in each child of a gambling father. Tiffani says the villian (is his name Patricio?) had taken advantage of her father for years. So Pats mom sees a match for her son in Tiffani who also was raised in a house of an abusive gambler much like she’s allowed her own husband to become.

she’s feeling guilty pats mom gets him out and plays matchmaker
