Your father maybe a smart man...but does he have Xray Vision ??? Most of the CV joint I have replaced are covered with a rubber boot to hold in the lubrication and keep dirt, water, etc out.
Take this car straight to a CV repair shop and let them have the final say so.
I would not drive it, loss of steering or control is dangerous !!!!
Use your boyfriends car or chopper in the meantime...the blot can walk!! ha ha. If not, get a cold slab of brew and sit by the road....a ride is only minutes away !!!
Cheers Lass...
