Know two lesbians who had been together about fifteen years, then one took up with a very much older man, to everyone's surprise. Nobody thought it would last, the ex was devastated and most friends sympathised with her. Next thing we hear they are expecting a baby, and again everyone was shocked, then after the baby was born they got married. Saw them today and the child is now two, and they are the happiest couple you could wish to meet. Feel guilty for genuinely thinking it would never last in a million years.
