Even May-April 15 romances may not work, depending on various other factors.In fact, it found that any kind of gap puts you at a higher risk for divorce.

Lovato and Valderrama are going on four years together, Lively and Reynolds started dating in 2011 before marrying in 2012, Olsen and Sarkozy dated for two years before marrying in the fall and Whitely and Statham have been dating for six years.
