Text my ex. I'm getting married.

Call your ex and say you're getting married. It is normal for him to ignore you. This shows that he still has you in his heart. After all, we were together and loved once. A day's husband and wife are grateful for a hundred days, and a hundred days' husband and wife are as deep as the sea. It takes a hundred years to help each other in the same boat, and a thousand years to share a bed.

He won't answer you. Let him go. His heart is bleeding and his eyes are crying. You can be friends before you get married, but you have no friends after you get divorced.
