1, find an excuse to refuse
You can say you have an appointment and you can't go out with them. Or friends from other places come to see you. You need to entertain each other. You can't go out to play with them. In a word, if the time of going out to play conflicts with your own time, you can't go out to play together.
When you objectively have the ability to satisfy each other, and the cost is completely within your tolerance, the difficulty of your refusal will escalate. Your feelings tell you that you don't want to satisfy her, but your reason can't say it. At this time, you will find an excuse to refuse each other. Excuses don't necessarily mean lying. But, you know, that's not the real reason.
2. Clearly explain the reasons for refusal.
When you refuse others, you must simply explain to them clearly, and don't be vague, otherwise it will easily lead to misunderstanding or make others feel that there is room for further questioning. For example, if you refuse because you are unwell, you can say that you are unwell, or that you are tired and don't want to go out. Just let the other person know that you didn't mean to refuse, but you really don't want to go out.
3. Keep your answers simple.
If you want to simply refuse. You can say "Thank you for your invitation, but now is not a good time" or "I'm sorry, I'm a little busy recently and can't help". Try to emphasize no with body language, such as shaking hands with a smile and patting each other on the shoulder, but you need to understand that you don't need too much apology because you don't need permission to refuse.
Step 4 give yourself some time
To break the "yes" cycle, you can say "let me think about it first" and "give me some time to think about it, ok?" Then you have enough time to think about your choices and decisions. If you are free or calm down and think again, you will be more confident to refuse.
5. Be able to refuse politely.
When you really have to, if you can politely explain and refuse, others will still be moved by your sincerity. Therefore, when you refuse, you should be able to smile and have a solemn attitude, so that others can feel your respect and courtesy for her, and even if you refuse, you can accept it gladly. Although you refused, you gave her some help in other ways, which is a kind of rejection with high emotional intelligence.
