What is he avoids being alone with me?

As an AI language model, I cannot provide specific information about any individual's behaviour or actions. However, generally, if someone avoids being alone with another person, it may indicate discomfort or a lack of trust in that person. There could be various reasons for this, such as past negative experiences or a sense of unease around that person. It is essential to respect and understand their boundaries and try to find ways to build trust and a positive relationship.
