How to be ‘ready’ to leave, but still work on the relationship?

[The6thQueen]

My husband cheated. I want to stay and work on it. Happened for two months this year, I’ve known about it for about two months.
The advice on here (and from my therapist) is to be ok to leave if things go wrong. But how do I do this? How do I invest in a relationship and be ready to leave it at the same time?

Hi OP
I'm going to come at this from another angle.
I have had a really difficult tine in my profession, including some traumatic events which has caused me significant mental health issues. I've had time off sick and gone back a couple of times. I've had therapy and medication to help get back to a place where I can do my job. Lots of questioning and angst over whether to stick with a job that can make me so unhappy. But I want to make it work and I don't want everything I've worked for to be for nothing (it's a lifelong career I've been investing in since I was a young teen). I am due to return again next month.
I will be going back trying to make it work. I will be working on myself, putting strategies in place, giving it my all, applying techniques to help me cope, etc etc.
I will also be aware that if I am unhappy, if this doesn't work, if after all this time and effort I am still struggling then this is it and I will have come to the end of the road, no matter how much I hoped for it to turn out differently.
I will simultaneously be giving it my very best with the hope that things work out, whilst preparing to admit its the end if it doesn't work (and part of that is considering next employment options).
I hope you see the relevance. You can give something your very deepest commitment, whilst also preparing for the possible outcome of this commitment not resolving the problem.
In fact sometime I think it is easier to let go if we need to, knowing we did absolutely everything we could to avoid needing to.
Some think I'm mad for not quitting sooner, some think I just need to get to a better place and I'll be fine. Just like there are differing opinions on marriages after infidelity etc.
It's up to you, but you can work on it hoping for the best whilst acknowledging that is not a certainty and preparing for other eventualities.
Good luck.

Thanks @PaySeeWhiTa, I completely get what you’re saying. It’s a good way to explain it.
I’m going to try to put it into action!
