Does couple therapy really works?

Your wife has to want to fix things for couples therapy to work, if she’s completely checked out then she won’t invest in the therapy

It will take both of you to make it work. I do recommend counseling both private and couples however unless you and she are committed to the process it will be a waste of time and money. Be open with your wife about what you want and feel and give her some space and time to let you know where she stands.

I think therapy is good if you both want to do it. If she doesn't want to save the relationship it won't help but you can use it to have a healthy co parenting relationship.
That being said you should be in personal therapy anxeity doesn't go away, it gets better but never really away. My fiance had the same happen and honestly if he didn't start taking medication and talking to a professional we wouldn't be together. Under stress he's still hard to work with but it's much more manageable now.
I'd tell your wife you feel guilty and feel that with professional help you think you can be better, and going to couple's therapy will give her a chance to talk about what she needs too. She's probably got a lot on her mind too and giving her the chance to let it out will be beneficial no matter what.

I agree with the previous posters. It takes both of you to make it work, but couples therapy does work because it covers a lot of ground that people need to think about.

I think your wife would appreciate knowing your honest feelings, about how you're sorry for all the fighting and mistakes and that youre willing to work on becoming a better husband and couple by going through therapy. Dont force her, but let her know you want to try to make it work.

If she doesnt want to do that, maybe just "try starting again", hang out like friends, go on dates. Do stuff together that slowly builds back up the relationship you once had. You said it drifted apart slowly, so there's nothing wrong to build it back up slowly. Relationships take time, especially when she probably might still be feeling some hurt from the past.

I'm sorry to hear. If she gives it a try it could work! Sometimes it's nice to just have a mediator that can help you guys communicate better.

I think the biggest question here is do you want to stop the divorce proceedings because you truly want to still be with her or do you want to stop them because you feel guilty of your part in the actions that you there in the first place. What happens the next time life its a rough patch? What steps are you going to take to creating lasting change? Sort that our first.

Maybe start with individual therapy and some mindfulness training. Then talk to your wife. As previous posters said therapy only works if you are both interested and committed.

My brother and his wife have had a tumultuous relationship from the start and started going to therapy, both together and separately, even while they were still engaged. As much as I don't care for my brother and HATE my SIL, they seem to be in much much much much better place now than they ever had been. They have now been married for 5 years and together for 9. They don't go as often as they used to, but do still go when things get a little rocky. There is hope, but she has to be willing to give it a fair shot for it to work.

Couples therapy is great - but you have the best results if you go in BEFORE problems become Big Problems. FH and I went last year, before we got engaged, and called it our "tune up", because it helped us communicate better, identify potential problems before they were even problems, and tackle the ones we already had that were growing Big. But, again, we went in as a strengthening exercise, not to "fix".

If your wife doesn't want to go, it's too late, I'm sorry. Individual therapy might be very helpful, though, particularly through this rough time.
