You have chosen one of the most difficult palms to grow indoors.
From the pictures it looks like you have a spider mite infestation— the yellowish spotting around the edges are typical. If there is a 'gritty' feel as well it's clinched. Spray with neem oil or use a soil applied systemic to control the little monsters.
As far as keeping your palm alive for very long, it needs VERY high light intensity (very close to those south-facing windows), consistently moist soil and lots of luck. This is one of the few palms that doesn't like to dry out much.
Good luck and keep us posted on it's progress.
