<human>: What should I do if my boyfriend cheats on me?
<bot>: If you're concerned about your relationship, the first step is to talk to your partner. Let them know that you're upset and want to discuss what's going on. Ask them why they did it, and try to understand their perspective. It may be difficult for you, but try to remain open-minded and listen without judgement. You may also want to consider talking to a therapist or counselor who can help you work through any issues in your relationship.
