I'm sorry @Strawberrina but it does sound too naive.
Why is getting OW out of the way the only thing you're focused on?
If you could send her to the moon, never to return, you won't suddenly feel happy and safe. He's done this once so you'll always know it's highly possible he'll just find another OW. Your head and nervous system will always know this.
You're doing something so many women do in this position and focusing all your anger on OW. While that's understandable you should be feeling a lot more anger towards your H. The fact that you aren't and you just desperately want to remove her so you can go back to a happy, loving marriage shows that you really aren't facing reality at all.
People can be very blunt on here which isn't nice but it often is the voice of someone who knows how this is going to play out because they've been there. However much you love him, the cold, hard truth is that he doesn't love you the same way. He would NOT have cheated if he did and would not continue to work with her. That is just a fact and I think people really just want you to wake up for your own sake as you only seem interested in moving her out of his life and going happily back to a loving relationship and it just doesn't work like that.
Women waste years in this kind of situation, feeling hurt, anxious, low and depressed. Constantly working on 'surviving' infidelity when there is so much more to life than just existing and surviving. Women thrive when they shed these cheating men who have caused no end of pain. Yes it's hard at first and you may love him but removing the cause of your pain and trauma means removing him from your life, not removing her from his.
