There is an art to enjoying NRE and allowing it to last and last!
Recognize it for what it is- it is infatuation and it is very common! It usually lasts between 6 to 18 months.
It can turn into an obsession if not managed.
An obsession can reek havoc on everyone involved and the relationship itself and start an emotional roller coaster.
It's great that you are involved with a guy that has experience in the lifestyle!
Sometimes there is an (unconscious) idea that NRE will evaporate or disintegrate when subjected to healthy boundaries, but I have found that the healthy boundaries will support the NRE and can extend it's life!
The key to life is in being fully engaged and peacefully detached simultaneously and authentically in each moment.
