What are reasons you think long term couples and short term couples break up?

[EvilAngel114]

Sometimes people fall out of love, try realize they don't have anything in common anymore, things get boring, they get to know "the real you", chemistry isn't there anymore, people change. They are a plethora of reasons.

[madgoat]

Over long term, people change. If they don't change and mould together then they inevitably grow apart.
Other common reasons are infidelity, children, and money.

that's a very good question
