Question: Should a difference in age be a deal breaker for a relationship?
Answer: It depends on how old you are. If you are 16 and he is 26, then “Yes” age should be a deal breaker. You are too young to be involved with someone 10 years older than you. You have high school and college ahead of you. A person who is 26 and wanting to date you is revealing his own insecurity and may even be a predator.
On the other hand, if you are a widow of 46 and dating a man who is 56, age difference is less important. You are both old enough to be mature. There may be other factors that would indicate you should not get married, but age would not be that significant. The general principle is that the younger you are the more important age difference becomes.
