1. Honest answer: If you think you have a good relationship with this girl and you want her to know your emotional state, then you can honestly tell her how long you have been single. This can also show your frankness and frankness.
2. Humorous answer: If you think that a direct answer may make you feel embarrassed or the atmosphere may be a little tense, then you can answer humorously. For example, "I have been single for several months, but I haven't lost faith in love." Or "I have been single for a long time, but I don't mind, because I am free to do what I want." Such an answer may ease the atmosphere and show your optimism and confidence.
3. Change the subject: If you don't want to answer this question directly, you can also choose to change the subject. For example, "I have a full life now and recently went on a great trip." Or "I have recently learned a new skill and feel very fulfilled." This will shift the topic to your life and interests.
No matter which way you choose to respond, sincerity and respect are very important. At the same time, you also need to respect yourself and consider the possible reactions and feelings of the other party.
