how about asking why the person you married 10 years ago and thought was the one is not the one now?
In my case i married 14 years years ago and separated 18th months ago. In my case my ex said she had fallen out of love.
So what did i want in a new partner.
In no particular order,
I wanted:
someone who had similar (or better level of intelligence)
someone i found attractive
someone who made me laugh
someone open and honest. ie not be afraid to tell me when i was being an idiot
As i'm 6 foot four i thought i wanted a taller woman (ie 5 foot 8 or higher) but girlfriend of last 11 months is 5 feet four that turned out not to be a deal breaker.
I thought a woman with maximum of two kids (again girl friend has three kids) and its not been a an issue
Someone who realized that as i had two children fifty per cent of the time to respect my wishes that they would not meet kids for approx 3 to 6 months. And that i could not meet up four or five nights a week.
Someone who was not looking to be "kept" by me.
Someone who had not ended previous relationship due being caught having an affair.
Similar age (plus or minus five years)
Did not want kids
The person i am with now we joke about that if we had met twenty years previously we would have ignored each other (we happened to be at same university but never met or had friends in common). She said back then she was interested in the cool guys and i would have been too "geeky".
No matter what the above "wish list" may have started out as it boils down to "someone i look forward to seeing/getting a text from/speaking to) . If the person is right for you you'll know it.
Its like asking what kind of house i would like to live in. I may answer Nice Victorian house with cellar, garden, original features, four bedrooms, garage. But can i be as happy in small three bedroomed cottage with a smaller garden, no garage. With the right person
yes. :-)
