This is someone ,male or
female,who claim to be in a relationship with only you ,but keeps you hidden from others. They do this is order to still appear single ,so they can continue to be sneaky on social media and dating sites. They
will tell you they are a private person in order to not acknowledge your relationship with them publicly. You
will never meet their family or
friends .In reality, they are hiding multiple relationships with the opposite
sex online .
These afflicted with this syndrome are usually a narcissist ,who tends to be loud , attention seeking, sneaky,and constantly plays the victim role to gain your sympathy . They are also selfish, entitled, and always thirsty for compliments and praise from multiple people in order to feed their fragile ego.
When you get suspicious and confront them about their behavior ,they
will gas light you.
They
will double down on the lies ,even after you present evidence of screen shots of said lies. They
will move onto the next best thing, because they sense you are pulling away from them . Once you end the relationship ,they
will quickly , generally within days , go public with the next best thing, in order to get one last dig in.
