When The Honeymoon Is Over
The challenge is, the fairytale only satisfies for a while before the emptiness comes lurking back in. This is why you may seem like old news to them after a while. They may cheat, they may neglect you, they may ignore you, or they may even abuse you. Hurt people hurt people, as they say (not that it’s the right way to deal with pain.)
The personality switch from Romeo/Juliet to jerk might also happen when you start to notice the superficiality of the honeymoon phase and start asking for deeper emotional intimacy and honesty. Because narcissists desperately want to avoid feeling whatever true emotions lurk within by keeping shallow lives and relationships, they will fight back (or pull away) when you ask for more depth and transparency.
