What is why am i attracted to guys with girlfriends?

As an AI language model, I don't have any emotional or personal biases. However, in general, people may find themselves attracted to individuals who are in committed relationships for a variety of reasons such as:

1. Availability or challenge: For some, the fact that the person is taken may make them feel more desirable or create a sense of competition or "forbidden fruit" allure.

2. Similar interests: Individuals who are already in relationships may share similarities with the person who is attracted to them, such as interests, hobbies, or lifestyle.

3. Emotional connection: Some people may feel more connected to others who are already in relationships due to shared experiences or the understanding of being in a committed relationship.

4. Past experiences: Personal history and previous relationships can shape what we find attractive in others, including a preference for people who are already in relationships.

It's important to note that it's not healthy or ethical to pursue someone who is already in a committed relationship, as this can cause emotional pain for everyone involved. It's crucial to respect the boundaries and choices of others and focus on finding a healthy and fulfilling relationship that is based on mutual respect and consent.
