Margot's husband Armando, a taxi driver, feels that his love for her has died and leaves her for a younger woman, despite their precarious economical situation.
Barbara is desperate to find a job to gain economic independence and thus escape her abusive husband, Jesus, and her mother-in-law, Matilde.
This cycle has repeated itself over and over for years, making Barbara incapable of studying, holding a job or even leaving the house without somehow exciting a violent outburst of jealousy from her husband.
Unable to live down the disappointment, she goes on to accuse Carlos of stealing the promotion and further tampering with her career, causing the couple to distance, with talk of divorce beginning between them.
Emilio also tricks Yorley, a low income woman who works as a maid, and her husband Mario by buying their house at a lower price.
From its premier on 21 January 2008 to 26 March 2008 it was the second most watched TV show in Colombia just behind its leading: dramatic and suspense telenovela Pura Sangre (Pure Blood).
El Último Matrimonio Feliz' new leading Novia Para Dos (A Girlfriend for Two Men) has not reached the high ratings Pura Sangre had and the competitor channel's Caracol TV strategy splitting its most successful telenovela in years in two parts placing another telenovela between the two parts has led to El Último Matrimonio Feliz to lose its original position on most watched TV shows in Colombia.
Nevertheless, the reinforcement of the prime time schedule in RCN network in the first half of May 2008 with action-policial procedure-oriented telenovela Los Protegidos (The Protected) has made all the telenovelas in RCN network including El Último Matrimonio Feliz to get the highest positions in a role, so El Último Matrimonio Feliz usually is getting the first, second or third place in the top of most watched shows in Colombia.
The quality of the story based on Colombian women's issues got a very much better reception than adapted version of Desperate Housewives (Amas de Casas Desesperadas) previously broadcast on the same time slot which became sort of a mistake for RCN network.
June 2008 #2 May 2008 #2 February 2008 #2 Since August 2008 this is the current schedule in RCN prime time, El Último Matrimonio Feliz is aired Monday/Friday at 9:50 p.m.
