What is he said his relationship is complicated?

When someone says their relationship is complicated, it typically means that there are a lot of challenging issues or unresolvable conflicts within the relationship. These issues could include things like frequent disagreements, differences in values or lifestyle, trust issues, past traumas or unresolved emotions, or difficulties with communication or intimacy. Saying that a relationship is complicated can also be a way of avoiding giving a clear answer to questions about the status of the relationship, as it may imply that the situation is too complex to neatly categorize as either "together" or "broken up." Ultimately, when someone says their relationship is complicated, it suggests that there are many factors at play that make the relationship less than straightforward and that resolving these issues may require significant effort and work from both partners.
