If you have moved on.
This may seem unnecessary, because you’re probably thinking, “there’s no reason to block an ex if you’re totally over it.” But, sometimes it’s the best way to say a final goodbye. Even if you feel like you have it all under control. This may not be the right move for you, but know that if your life is going to be easier by blocking an ex, it doesn’t mean you’re weak or still have feelings for them. It may just mean you’re closing a chapter in your life and getting ready to start a new one.
