Inheritance question

My sister left me around 310,000. My spouse left me before my sister died and filed for separation. We were married for 23 years. We have been legally separated for a year now and went to mediation. My husband is refusing to pay any alimony b/c of my inheritance.

What is the law an nc regarding inheritance. Does my inheritance have an effect on my spouses ability to pay alimony and retirement? I ama teacher making around 30,000. My spouse is an engineer making over 90,000.

Separate property is a factor in the award of alimony.
