Rob, my experience with counsellors is that they don't give advice. You turn up unhappy with your marriage and sex life end up discussing your parents. Counselling certainly didn't help me when my marriage was failing.
What would have helped me when my marriage was ending would have been a group of strangers telling me what they'd do if they were in my shoes. And I'd quite enjoy having the contradicting opinons to consider.
Lastly, people get what they pay for. If they want to pay nothing, then they get advice from a bunch of unskilled strangers on the internet. If they want professional advice, they will see a professional.
Never regret anything that has happened in your life. It cannot be changed, forgotten or undone. So, take it as a lesson learned and move on.
