Feeling Like the Third Person Without Any Proof [Cuckold]

I’m a 19-year-old girl from Singapore, and there was a period in my last relationship when I started feeling invisible without fully understanding why. My boyfriend hadn’t done anything obviously wrong, and that was what made it so confusing. He had become close to someone new, and while I trusted him, I couldn’t ignore the fact that he seemed happier talking to her than he did talking to me. Every time we were together, I caught myself comparing the way he reacted to my messages versus hers. I hated that version of myself because I’d never been a jealous person before. The worst part wasn’t thinking he would leave me it was wondering whether I was slowly becoming less important in his life. I spent weeks convincing myself I was overthinking everything, but the distance between us kept growing. Eventually, I realized that relationships aren’t damaged only by betrayal; sometimes they fade because two people stop making each other feel seen. Looking back, I learned that communication matters far more than assumptions, and that insecurity grows fastest in silence. I still think about that chapter of my life because it taught me how easy it is to lose yourself while trying to hold on to someone else.
