Connor with car running squeeze the top radiator hose, if it is solid and highly pressurised then there is a fair chance the head gasket may have gone. If not you have a problem of some sort in the cooling cct. I take it there are no leaks around the radiator end tanks?
If not take the thermostat out completely put everything back together and try again if everything is ok and there are no issues due to over heating then you know you just need a thermostat.

The radiator would spew out water because the car was boiling hot, that is entirely normal. Your head gasket is most likely fine. I went through a multitude of overheating problems when I got car, ranging from cracked hoses to a cracked rad to a blocked thermostat, headgasket was still fine.

And the needle being halfway is not a very good indicator sometimes, if there is no water in the system, the temp might show normal when it is severely overheated.

After the thermostat is fixed, inspect your hoses carefully, it's very likely some will have been pushed to failure by the high pressures and temps during overheating.

If the top hose wasnt pressurised it will most likely be that the head gaskets and the heads are ok but it is really only an indication. With the cap to the expansion tank off and the car running can you see water flowing back into the expansion tank, if so then the pump is probably ok. The fact that the radiator was cold would make me suspect the thermostat is stuck closed. So running without the thermostat should give you a short term fix.
