Sticky situation

Okay so I'm expecting negative comments but hopefully I can get some advice.

So I've been with my husband going on 3 years. We haven't always had a great marriage but I do love him and it's not always bad.

Before we married I was in love with someone for years and we were together on and off. He chose someone else. So i chose the man I'm with now. Although i still had some love for the one who didnt choose me. About 2 months before I got married this man confessed he still loved me but I had already (or so I thought) moved on. I got married. So about 6 months later the guy confessed it to me again face to face.

For 2 years I've tried, prayed, done everything to forget him but its caused me to lose sight of life.

I confessed to my husband that I loved this other guy still but I also loved my husband. And he was surprisingly okay with it???? Like no fight or anything.

So my question is, what do I do next? I know it's a crazy situation and most people will judge but I'm looking for some sort of advice to move forward.
