Welcome, @Quinny , it's good that you've joined, where you can find people to support you in what you're going through.
I'm sorry to read about your husband's betrayal, and how lost you're feeling. I can only offer my sympathy. I have had to rebuild my life (for different reasons than yours), and it can be done, with new friends made and new interests, etc. But the breakdown of the old life is very painful and brutal.
I hope you find the forums supportive. A handy forum tip is if you type @ and then click on a member's name in the drop-down box, they will receive a notification that you're replying to them.
All the best, @Quinny ...
