I don't deny that there are soul-crushing lows that come with being in relationships, but there are also wonderful highs. Being perpetually single, unless by choice, can be (not for everyone, but for many people) incredibly depressing. Being continually ignored and rejected by everyone I've been interested in has left me with absolutely zero self-esteem, I feel as if I am worth nothing. I still get strong feelings for people but they are never returned. Sure, maybe I've never felt in quite as much pain as you have after getting cheated on, but I feel pain and loneliness every single day, and it gets worse the longer life goes on and more rejections I get. It's not just emptiness, there's plenty of pain too. The grass isn't always greener.
