what is Alberts dillema of his planned marriage with madamoiselle Danglars?

This has to do with chapter 40. Albert returns from Treport and visits Monte Cristo. Albert states that the thought of living with Mademoiselle Danglars every day horrifies him. Monte Cristo reassures Albert by stating that Monsieur Danglars may back out on his word in favor of another husband for his daughter. At this Albert wonders why he is not good enough for Danglars, despite his desire to be rid of the duty to marry. Monte Cristo reassures Albert Danglars is a man of bad taste, and thus prefers another to Albert.
