In the late 1960s Clapton and Harrison became close friends, and began writing and recording music together. This is when Clapton fell in love with Boyd.  His 1970 album with Derek and the Dominos , Layla and Other Assorted Love Songs , was written to proclaim his love for her, particularly the hit song " Layla ".  When Boyd rebuffed his advances later that year, Clapton descended into heroin addiction and self-imposed exile for three years.   Boyd moved in with Clapton and married him in 1979.  Her struggles within the marriage were masked by her public image with Clapton. Boyd drank, and admits to past drug use, but she never became a drug addict like Clapton did.  Boyd left Clapton in April 1987, and divorced him in 1989. Her stated reasons were Clapton's years of alcoholism , as well as his numerous affairs,  including one with Italian model, Lory Del Santo .  In 1989, her divorce was granted on the grounds of "infidelity and unreasonable behaviour".  Boyd was also the inspiration for the songs: " Bell Bottom Blues " and " Wonderful Tonight ".
