Hi and

It's good that you found us. Ten years is a long time! How long ago was the breakup and how do you feel about it? Has the knowledge of his diagnosis altered your view on things at all?
I visit him for a few hours during the day on a weekend. But I’m confused if that’s good or bad.
What is your intention regards the r/s? Are you wanting to move on or do you see the possibility of reconciliation? Do you both have a clear understanding of that?
You've come to the right place. We can help here, whatever direction you choose to take. I'd encourage you to read all you can as the information on the site is reliable. You'll find some excellent articles under the Tools and Insights tabs on the main menu bar at the top of the page. Also each board has it's own Lessons to the right of the screen to help us to make the best of our individual situations. Finally, I'd advise you to read and post in other threads too, as the wealth of experience and knowledge here is a huge advantage.
I'll look forward to hearing more from you. Share as much as you feel comfortable. We are all family here and support one another.
Love and light x
