The old "half your age plus seven" rule is a guideline, not a rule, and doesn't account for individual differences or modern contexts. Focus on communication, life alignment (kids, career), and shared values, rather than just the number, say experts.

Couples with an age gap of 1 to 3 years (with the man older than the woman) were the most common and had the greatest levels of satisfaction. Relationship satisfaction decreased slightly for couples with age gaps of 4 to 6 years and continued to decrease for couples with an age gap of 7 or more years.
1. Lack of Honesty. Often when we think of honesty, notably honesty in marital relationships, we think of a very tangible “where were you last night” kind of honesty. While this is obviously critically important, there are many other kinds of dishonesty that can destroy marriages.

The "72-hour rule" after a breakup generally means implementing a period of no contact for at least three days (72 hours) to allow intense emotions to subside, enabling clearer thinking and a less impulsive reaction, whether that's reaching out or making big decisions.
