My ex of 6 years broke up with me 10 months ago because he wants kids and I don't. Three months later I started dating someone else. He recently friend zoned me, now all my pain and feelings came back for my ex. Now he's the one who is dating someone else. She has two small kids and it hurts me to see him with her and the thought of them starting a family. We talk here and there and hung out twice. Now I just want to tell him how much I miss him. How I miss us. Should I tell him how I feel? Or just let him live his life with his new girlfriend and work out these feelings on my own and move on?
