Aquarius men can be described as a type that doesn't really obsess over romance. Many of them transition from friendship to love naturally, finding themselves in a relationship without realizing it. Therefore, they are unlikely to engage in one-night stands.
Therefore, when an Aquarius man shows interest in a woman other than his girlfriend, it may not be cheating but a possibility of changing feelings. Initially, a close colleague or a hobby friend may become a potential new partner, leading to a distant relationship with his girlfriend. By the time the topic of breaking up is broached, he may be seeing someone else.
