Married and crazy about my ex...

I’m married and I’ve just recently got back in contact with my ex. Just the thought of him drives me insane and makes me miss him so much. He lives in another state and I wish I could see him and be with him. He was my first in all senses. I miss him and I’ve always loved him. I haven’t seen him since 2008😔

I’m happy with my now husband but there is no intimacy. He’s an amazing father and works really hard to give us a good life. But I’ve always felt something is missing and now I know what it is. He’s not my ex. I’m so torn on what to do.... I am not 100% happy with my current marriage but I love him to death and I believe in until dearth do us apart. But my whole life I thought I would spend my life with my ex. I would appreciate any input or advice
