Dating partners who fall in love tend to how much they liked each other when they first met. dating partners who break-up tend to how much they liked each other when they first met.

Over-estimated, under-estimated

Explanation:

When people first meet they tend to overestimate their feeling because they are still extremely physcally attracted to one another and the reality of how the other person is like has not really surfaced , they are still in a phase where they want to please each other and impress one another. When these goofy bumps and butterflies are all gone and the other person start to show who they are everyone start to realise they might have been more in-loved with the idea of what the other person is hence they overestimated their feelings.

However the opposite occurs when people break up , they tend to focus more on the negatives and ignore the positives and when it a over it sinks in and they start to realise that they might have loved the person more than they imagined.
