What is emotional detachment?
Emotional detachment is when someone avoids their emotional connections.
what else can you tell me about this?
Emotional detachment is sometimes just temporary like a reaction ot highly emotional circumstances
oh it does not seem to a  serious condition
rather than an inability or difficulty in doing so, typically for personal, social, or other reasons. In this sense it can allow people to maintain boundaries, psychic integrity and avoid undesired impact by or upon others, related to emotional demands. As such it is a deliberate mental attitude which avoids engaging the emotions of others.
This detachment does not necessarily mean avoiding empathy; rather, it allows the person to achieve the space needed to rationally choose whether or not to be overwhelmed or manipulated by such feelings. Examples

It refers to the evasion of emotional connections. It may be a temporary reaction to highly emotional circumstances or a chronic condition such as a depersonalization disorder.
Emotional detachment can be a positive behavior which allows a person to react calmly to highly emotional circumstances. Emotional detachment in this sense is a decision to avoid engaging emotional connections,
