Roverman,
To put another perspective on it I’ll give you my side as I was effectively in the same position as your wife.
I’d been with my ex from being 15, engaged at 17, married at 21, no kids and we just ended up like mates.
There was no-one else involved in the split but I just decided after YEARS of thinking about it to end the marriage it wasn’t taken lightly, or done with malice but there was no relationship left from my part and I didn’t feel that way about him any more and we led very separate lives.
We’re friends again now after 3 years but for a long time it wasn’t possible as he still had strong feelings and I didn’t want to hurt him any more than I’d done already.
Its a very very very hard thing to do to be the brave one and say its not working especially if the other person would just have continued with the relationship as it was for whatever reason.
I hope I haven’t said anything out of turn just trying to say that it takes alot of guts to let someone go to be with someone that will feel that way about them and you will find someone just like I did and he did also.
Good luck with everything
