When there is mutual caring for the well-being of the other and mutual interest in what is being shared then engaging with another- whether physically (in person) or through technological devices- is healthy. When there is not a mutual concern for the well-being of the other or mutual interest in what is being shared then engaging with the other is unhealthy and it is wise to disengage.
We find much interaction on the internet and even in person is unhealthy. It is one person playing ego games with another with no real interest in the other or their well-being. In such cases it is always harmful to continue the transaction. You will know this by how you feel. If you feel poorly when interacting with another then your well-being is not being looked after and disengagement is the wise thing to do. When their is mutual care and interest you will know this because you will feel good in your interaction with the other. In such cases continued interaction, until one or both are ready for a break, is healthy. Bear this in mind when interacting with others in person or via some other method.
