Spouses abandoning their families and obligations

My husband provides care for his aging parents.  They are quite dependent on him.  My father-in-law is, admittedly, bossy and hard to get along with.  My husband said yesterday that his father has expressed fear of my husband leaving, and my husband said he had actually told his sister that he would walk out if his dad gets too bossy. 

This morning, I'm wondering if my husband bragged to anyone when he withdrew from me and stopped providing me with emotional and financial support. I feel bereft.
