Before I met DP (10 years ago) I had a bit of a ‘thing’ for someone at work. We were both single. Both shy, and I have no idea if he ever thought of me as anything but a (distant) work colleague.
He never married or had children.
He retired a few years ago and I have never seen him since.
BUT every now and again I’ll have a period of a few weeks were I dream about him. In the dreams we are very close and I either feel terrible for hurting DP, or I totally dismiss DP from my life.
I feel so guilty when I wake up even though DP is obviously totally oblivious!
I love DP. We have a lovely life and he’s the kindest, most generous and supportive partner I have ever had. I would never hurt him. We have a lovely future planned and I can never see us not being together.
But, and I hate to admit it, I quite enjoy the dreams 
So why does this happen? How do I stop this??
I have often wondered what my life would be like if I we had ever got together but I have never pined for ‘what might have been’
I’m almost 60 for goodness sake! Is this normal?!
