The song "Amnesia" by Amerie explores a tumultuous relationship that is characterized by a cycle of fighting, wishing for better, and struggling to say goodbye. The lyrics suggest a pattern of repeating mistakes and facing obstacles that have been encountered before.

The line "We shouldn't have too much fun" implies that the relationship is filled with excitement and enjoyable moments, but this excessive joy might contribute to the recurring issues. There is a sense of urgency and a desire to escape the difficulties by running away ("I say we run for it, run for it, run").

The chorus reveals a conflicting desire between wanting to do things correctly and wanting to enjoy freedom and independence. Both parties express a desire to do things right this time, but their actions suggest otherwise, with one person staying out all night while the other wants to work things out.

The mention of "catching amnesia for fun" can be interpreted as a metaphor for deliberately forgetting past mistakes or problems in order to enjoy the present moment. However, this temporary relief from the past doesn't resolve the underlying issues and is only a temporary escape.

The lyrics also touch on jealousy and insecurity ("All other girls I won't mention, we know you love the attention"), suggesting a lack of trust within the relationship. This further reinforces the notion that breaking and making up is a repeating pattern.

Overall, "Amnesia" portrays a toxic relationship stuck in a cycle of conflict, temporary relief, and the inability to learn from past mistakes. The song highlights the desire for a better, more stable relationship but acknowledges the challenges and emotional baggage that hinder progress.
