I've never been left for an OW so this pot is not coming from personal bitterness but I just have something to say about all this.
First of all when a woman raises your children and leaves her career to do it, it's pretty appalling to complain about her not working. She might well be able to get a job of some sort, but it's likely she gave up the idea of a fullfilling career to be married and have a family. I am not saying she can't be expected to pitch in and maybe get a part time job doing something less qualified who would accept someone after a 10 or 15 year career break but speaking from experience it's not that easy and also quite daunting. It's also a lot of work looking after kids and a home.
Second of all, I think if you feel all these things about your wife - the decent thing to do would have been to have told her and discussed this - not start flirting and falling in love with someone else. I do understand your needs aren't being met in your marriage but thre's a right way and a wrong way to do things and your way involved looking at some shiny new, "stunning" woman who's all the things your wife isn't and it's an unfair comparison.
Third of all, if you're telling a woman you're in love with her - it's not a case of "nothing has happenned". Fro my perspecitive I'd be more upset about my husband doing that, than if he'd had sex.
You might wellbe a very nice man, and your wife ight wll be a demon or incompatable with you but I suspect what's more the case is that you have partially been responsible for your wife becoming who she is.
It was partly down to you that she had another baby, unles she impregnated herself
Partly down to you she is not an indepenent career woman.
Hardly her fault she is not 27 and stunning.
And also you know...if you live with and do these things (like watch TV in a separate room) then you are equally culpable. It sounds to me like you hav been unhappy for ages in multiple ways and instead of doing something aout it you have cast all the blame elsewhere, which is really emotionally unhealthy.
Maybe your marriage has broken down and it has no love and you have a chance for "love" with this new woman but it would be fairer if you'd left your wife for the right reasons - to make a life on your own - rather than feeling like some young hottie is going to be the answer for you.
She might well be. You get a fresh start. You get someone young. Someone independent. someone without the history or the decade of negative memories but I hope in fairness to your stbxw that you can sit down and think about what role you might have played in having been so unhappy for so long.
I am always a little sceptical of all these men who believe some woman who happens to be 10 or 20 years younger, and invariably happens to be "stunning" is somehow a better, nicer, more loving, more compatable person than their wife. Truth is probably that most of the time what makes them so appealing is the very fact that they are NOT your wife and when envisaging yourself with the new woman, you become a new man.
What I am saing is that men can often erase a life like an etch a sketch, and it is laregly due to the fact that they reach middle age and feel unhappy with things. They have spent so long not fixing what they have that they have lost the love they once had for their existing wife.
Having the young hottie at the office that all the men fancy might seem really amazing right now - but to be she won't ever be as amazing as the person who spent 15 years raising your fmaily with you, and that is a very sad thing to give up and to lose. It;s so easy to re-write history when it suits us to do so.
We are only human...but it pains me to hear all the blame in your posts. I am not trying to have a go at you, but maybe think about how she might feel as well. you might not love her anymore, but you married her and ultimately, shagging or not you utterly betrayed her.
