If you miss true love, can you start over?

I haven't been able to get rid of the pain for three years. I think about him going to bed every day. When I woke up and opened my eyes, I was lost. If it's your fault, you should admit it and talk to him. If he loves you, you will be fine. If he can't forgive you and make you suffer so much, then maybe this relationship is meaningless. Relax, there will always be someone to accompany you through life without him.
