What if there are handsome guys in the girlfriend tour group?

Build trust, communicate, strengthen intimacy, etc.

1. Building trust: Trust is the cornerstone of a healthy relationship. I believe my girlfriend will be loyal to me and have the ability to handle her feelings well. Don't worry too much or doubt your behavior.

2. Communication: communicate honestly with your girlfriend. Tell your girlfriend that you are worried, but avoid being too jealous or controlling. Listen to your girlfriend's views and feelings and try to solve them.

3. Strengthen intimacy: increase mutual trust and contact by strengthening intimacy between two people. Spend more time together, share each other's interests and experiences, and build deeper emotional ties.
