No, I don't believe sharing is the key, although it helps. I my opinion time is only the real key...

And probably excluding oneself from the whole relationship, what I mean is not trying to keep tabs on him/her

Any new opinions out there ?

Hi Ithappens- I hope you re well.
Here's my two cents:
We re all different people and react differently- I ve always been the so called dumper but only when I ve got to the point when I ve realised that no matter how much time love and loyalty I put into the relationship it s not making me happy. So my breakups have been painful. I do however bounce back pretty quickly-a couple of months down the road I'm fine again. As for the guys I broke up with I couldn't tell you-its been NC forever.
I have a guy friend though whose wife left him five years ago and he s still not over her. Yes he s just started therapy so fingers crossed.
Interesting thread,thanks
