This sounds like battery to me too. When jumping, did you connect to terminals under the hood? Also, you should keep the cars hooked up for maybe 5 mins. with donor car revving slightly. Then try to start.
Bet it will...or you could try jump starting.
Check date on battery...if old...it might just be its time.
