If you have a blown head gasket, yes, the fluid might leak from your gasket onto a cool exhaust and you might find dripping fluid that has traveled from a blown head gasket by way of path of least resistance to your catalytic converter, so that it drips when your car is cold but always steams away coolant while you are driving.
I guess the best thing I can tell you is that, unlike many cars, your problem cannot be maintained. You need to fix the leak right away or give up on the car. This engine cannot withstand even moderate overheating. The head gaskets go if the engine is overheated. Other than that, the coolant system is difficult to flush, and it requires a long time to flush the system completely. A Jiffy Lube version for ten minutes is not going to do it.
