For some people, even a small rejection makes the whole day hard. The other person only said no because the timing did not work, but the one who was turned down takes it as being rejected as a person.
They interpret what was rejected differently. If they take a no to their suggestion as a no to themselves, they remember the same words far longer.
Another reason is that they predict what comes next. After one rejection, they expect the same next time, and to avoid being turned down, they stop asking at all.
They do not know what they did wrong. They explained their situation when they said no, and when the mood still becomes tense, they cannot tell how they are supposed to say no in the future.
In the end, they stop saying no. Agreeing to everything to avoid upsetting the other person means they cannot keep their own schedule, and pushing themselves that way, they come to find the relationship tiring.
They differ in how readily they notice negative signs. People who notice small changes in tone and expression first have more information, so they also reach negative interpretations faster.
They also differ in where they get their sense of worth. For someone who gets it from other people's reactions, a rejection is a judgment. For someone who gets it from their own standards, a rejection is only a scheduling matter.
The person saying no gives a reason and suggests another time. Saying today does not work but next week would means the other person does not take it as a rejection of the relationship with them.
The person who was turned down checks their interpretation. Asking once whether the other person is avoiding them or simply cannot make it gives a more accurate answer than guessing alone.
The one who is sensitive to rejection stops suggesting things first. When they stop making suggestions to avoid any chance of rejection, the same person always ends up contacting the other first, and the other person mistakes this for a loss of interest.
The person who says no gets tired of being careful. Choosing every word makes it hard to talk freely, and a relationship where talking is not easy is hard to maintain.
A strong reaction to rejection does not come from a weak personality. It depends on how readily someone notices small changes in the other person and where they confirm their own worth.
The relationship analysis includes sentences better left unsaid between the two and sentences to use instead. It shows in advance which words to avoid when saying no, so the other person does not take it as a rejection of the relationship with them.
