Today when I was on highway, I saw the temperature gauge going up. I pulled over right away and added some coolant I had in my trunk. I had this problem about 6 months ago and adding some coolant helped the problem go away until today.
After I added the coolant, I saw that it didn't improve at all. I drove to the closes gas station, got some coolant and added more until it topped off.
Then I drove home and it was fine.
After an hour when I left home, I noticed that pool of coolant under the car. I thought I might have added too much coolant and that was coming out.
I started the engine and when I was on the road I saw that engine was heating again. I stopped, added more coolant, but I noticed that coolant was dripping very fast under the engine.
I drove to work parking lot and when I stopped, I saw that my car left a trail of coolant on the road and it was leaking under the engine as if someone turned on the faucet.
What does that mean? A hose?
it can't be radiator. Radiator was not leaking. Can it be water pump?
I think if it was gaskets, the dripping would be slower. Am I right?
Well, it sounds like you have already mentioned most of what it could be. It sounds like you started out with a slow leak that just got worse. I would first check under the car to see the general area that the fluid is leaking down from, then open the hood and look in that area to see if you can see a hose leaking. If the fluid is not coming from the radiator area, then most likely you do not have a radiator leak, one thing to remember, the fluid can be leaking down onto your frame, and running along it and then dropping down onto the road, so check to make sure that is not happing. 9 times out of 10, it will be a bad hose. But you should not drive it if it overheats, as you can end up warping the heads form the heat, and blowing a head gasket. Then what would have been a $20 or $30 fix can end up running into the thousands. Good luck.
