My first marriage was based on this (note the first
)
Ex = best friend, we wanted to stay together so got it together. sex tapered off after a couple of years and we lived like brother and sister. Eventually we split up but it took us ages because we loved each other so much. No kids.
Conversely, I fancied the pants off dh right from the word go. The 'friendship' side of things developed from there and we've been together 13 years. Sex life still great and he's a much much more suitable partner and brilliant dad. 2 kids.
I ask because friends of mine are a bit like this at the moment - best friends abd really well-suited in nearly every way but one wants more. Can it ever work out?
