He Already Had a Family
Getting engaged to the love of your life is a dream come true for most women. This OP even left her life and work behind and moved across the country to be with her fiance so they could build a new life together. Imagine her shock and horror when she did some digging after he didn’t come home one night and found out that he had a secret family living just a few miles away.
How could he pull off this stunt for so long? More importantly, why would he put her and his other family through all this turmoil? Thankfully, she discovered his lies before it was too late and canceled the wedding asap!
