I have 3 very close male friends who are in these types of relationships .... the male is vv social, real party animal, great fun, life and soul of the party etc - highly intelligent, loads of friends, loads of diverse interests - and the partner is Miss Mouse - no mates, no interests or other social life, dull, clings to the male....is the only woman at all male nights out....totally gets into the music/football team/whatever of the male - having had zero interest or the opposite tastes previously (I know 2 of the women from before).....
