Thank you for bringing up the sexual/hormonal component, one which I mostly skipped over in regards to the honeymoon stage. It's very interesting to observe how our perspective can radically change once the initial buzz has subsided.

Expectations are also a major obstacle to overcome, as they can alter our view and make it difficult to face the reality in front of us. And a key component to a successful relationship is when both partners are independent and co-exist as individuals instead of becoming overly co-dependent, which can lead to jealousy and distrust.
