Leaking coolant- 93 Probe GT- 205k miles

Hi,
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?

or gaskets?

I think if it was gaskets, the dripping would be slower. Am I right?

thanks a lot for your assisstance.
