"Je ne t'ai pas laissé. J'ai juste avancé."

Simplified Meaning:

When someone says "I haven't left you. I've just moved on," they mean that they still care about you, but they've decided to continue their life in a different direction. Imagine two friends who grew up together. One friend gets a job in another city and moves away. They are no longer physically present, but they still think fondly about their friendship. They haven't abandoned their friend; they've just chosen to pursue a new opportunity that leads them elsewhere. In life, people sometimes need to make changes for their own growth or happiness. For example, a person might end a relationship because it’s no longer healthy for them. That doesn’t mean they don’t care about their former partner. They might still hope the best for them, but they know it’s best to go separate ways. This idea can be helpful in understanding that moving on doesn’t equal not caring. It's about recognizing the need for personal growth and new experiences. By moving on, a person follows what feels right for them, yet carries the memories and feelings from the past with respect.
