Ok here's the thing my Car wouldn't start tried several days in a row for several minutes. So i changed the plugs and it still wouldn't start. So i got my dad to try to jump me off. Cranked right up. Now my question is could my battery just get "run down" if i don't drive my car but like once a week?

 

Most all rechargeable batteries loose 1% of their charge per day just in storage.
Plus you have some constant trickle loads - clock, radio memory, ECU memory, alarm etc..

 

Take the battery and have it tested. My '89TII sits for weeks (in a garage) and have never encountered a dead battery when trying to start. Battery could possibly be weak, and therefore not hold a charge for an extended period of time. You might also have something draning the battery when sitting. Better check that also.
