Yes, it is not uncommon for twin flames to be excessively obsessed with each other. This is because the twin flame relationship is the deepest and most intense soul connection that two people can have. The depth of this connection often leads to an all-consuming obsession with each other. This can be both a good and a bad thing.
On the one hand, this level of obsession can lead to a beautiful and fulfilling relationship in which both partners are completely devoted to each other. On the other hand, this level of obsession can also lead to an unhealthy and codependent relationship in which both partners become overly dependent on each other. It is important to find a balance in the twin flame relationship and to make sure that both partners are still able to lead healthy and independent lives.
