I miss the friendship that I had with my ex, is that normal?

Anonymous
My ex were long time friends before we started dating, after we broke up we remained as close friends. I’m now ready to start dating again and have been dating a new guy for a couple of months now, I’m open to him about the fact that I’m still friends with my ex. He wants us to be exclusive but he said he’s uncomfortable with my ex still being in the picture.

I then talked to my ex that we need to cut off contact out of respect for my new relationship and my ex is fully supportive of it but why I can’t I help to not feel like I’m losing one of my longest and closest friends… I’m kinda grieving the end of the friendship and I miss my ex as a friend. Is this normal? What can I do to stop feeling this way?
