Personal opinion----I say discontinue the P/T---unless it is really helping your everyday mobility and really helps with the pain.
Did your doctor tell you to continue with the P/T?---in which case, you should probably do what the doctor suggests----but I would also say, in a way, that it's kind of like throwing money away at this point---BUT that's only if it's not really making a significant difference in how you feel on a daily basis.
You could do the exercises that they teach you, at home for the next 6 weeks----that's an idea. And probably not a bad one in any case, whether you discontinue the actual P/T with the therapist himself, just to help maintain some of the strength in your leg-----You probably already have some muscle loss with the treatments you have already been going through.
In any case----I wish you the best of luck----I hope this time you are healed for good!

Jane and I posted at the same time---The crutch lessons, if you need them, are a really good idea!
P.S.----Enjoy all the play time you can get --with the kids and the puppy!!
