Answer:
The best answer to the question: What factor affecting self-disclosure can be identified here, would be: Grayson is avoiding disclosure for a variety of reasons.
Step-by-step explanation:
When talking about ourselves, and communicating our innermost, and most intimate thoughts, situations, or feelings, there are a lot of things that can get in the way. Because Grayson´s parents´ divorce is still such a sore subject, it is evident that Grayson is not ready to open up about it, not even with a significant other. What Grayson is doing is avoidance, trying to avoid disclosing a part of him that he cannot yet put into words as he is still dealing with the emotional upheaval of it all.
