Why do people think negatively of someone who moved onto a new relationship after a long term relationship?

I moved onto a new relationship after 6 months of my long term relationship. I feel like that is enough time to move on and it was not a rebound. But then people would judge and say things like I degraded and stuff. Or I moved on too fast. Maybe he is less attractive than my ex but we are more compatible and he treats me a lot better.
