On our wedding night, my husband Grayson's sister-in-law, Scarlette, stumbled drunkenly into our bridal suite and threw her arms around him, refusing to let go. "Kayla, my husband died young, and I really just want a child. Please, lend him to me for one night," she cried through her tears, shoving a toy into my hand. "I promise I'll return him tomorrow. And if you get lonely… you can use this to comfort yourself." I stood there, dumbfounded, my gaze shifting in confusion to Grayson, who was already helping Scarlette steady herself. "You're really going to sleep with her?" He avoided my eyes, his tone strangely urgent. "Don't overthink it. She's drunk and talking nonsense. I'll take her back to her room to rest." As he started to leave with her, I stepped in front of them, blocking their way. "Grayson, it's our wedding night tonight. Are you seriously going to walk out with her?" His expression darkened as he pushed me aside. "You're my wife now—try to be more sensible. Don't get jealous over something so trivial." Then, carefully, he guided her out of the room. I wanted to run after him and stop them, but when I saw the deep concern in his eyes as he looked at her, the truth finally hit me. The love this man had for me was no longer mine alone. And if that was the case, why should I cling to a marriage that had already soured? I might as well walk away with my head held high.

Out of the blue, my younger sister posted the result of her pregnancy test. The caption?

"Congratulations. Maybe you can keep my husband too?" My husband's reaction? He blew up and dismissed me. "I just donated my seed to Cara! Don't make a scene, Barb!" Oh, I'll make a scene.
