I've been married for five years. living with my spouse for two years of the five. can i file for spousal support or for part of his pension?

I moved from long island n,y, where we got married because of emotional distress and abuse. No legal separation or divorce has ever been filed. We lived together for two of the five years we've been married. I consulted an attorney before i left and he said that even at two years i can go for part of his pension. He retained all marital assets.
