Pup used to post under another name, but also he has a thread somewhere else that gives the links I think. I am not sure if he started a thread in piecing but didn't use it much, as most folks know him in newcomers and infidelity.
I exposed in my sitch and you can see from my tag line that my M is still together and going strong. I won't give details though as everyone's experience is different and my sitch won't be relevant to you.
You have to do what is right for you. Your M won't heal whilst there are three people in it, but there are different ways to try and save it. Exposure works for some and not others.
It would be useful to hear from some posters who exposed and it didn't help save the M, so you can see the pitfalls of this route also. Trouble is, they will have probably moved on and stopped posting.
