I might have just made the biggest mistake of my life and there's no way to undo it.

The love of my life and man who I want to spend the rest of my life with started to propose to me and I stopped him because I didn't like where he was doing it. How could I be so stupid???? I was so obsessed with it going exactly how I wanted that I interrupted him and made us move somewhere else. Of course he didn't ask again and is heartbroken. I'm moving back to my mums and he wants me gone. I can tell he doesn't love me anymore and it's killing me. The perfect man of my dreams doesn't love me anymore because I was so selfish and stupid and interrupted him as he poured his heart out.
