Anyone else ?

I’ve been in a loving relationship for 5 years. I’m perfectly happy & content. I have a beautiful family & we’re trying to have another baby.

I go through phases of missing somebody from my past. I haven’t talked to him on over five years, we never really dated it was more of us just being drawn to each other and when we needed a friends with benefit. But we we had years and years of history and he is who I lost my virginity to so I don’t know if that’s why I always find myself thinking of him.

Am I crazy for feeling this way? I feel like everybody has someone they’ll always have in the back of their mind..

I’m curious to know if anyone else is like this.
