What is why did he kiss me if we are just friends?

Navigating relationships and understanding why someone might act a certain way can be complex. If a friend has kissed you, there could be several reasons behind their action:

1. Romantic Feelings: They might have developed romantic feelings for you and saw the kiss as a way to express their emotions. The boundaries between friendship and romantic interest can sometimes blur, leading to such actions.

2. Momentary Impulse: Sometimes, people act on impulse in the heat of the moment, especially if the setting was emotionally charged or felt special (like a celebration or a moment of vulnerability).

3. Experimentation or Curiosity: They might be exploring their feelings or curious about any potential romantic connection between you two. This doesn’t necessarily mean they want to change the nature of your relationship, but they might be trying to understand their own emotions.

4. Miscommunication: They might have misinterpreted signals or assumed there was a mutual interest. Mixed signals can often lead to misunderstandings about each other's feelings.

5. Alcohol or External Influences: If substances like alcohol were involved, it might have lowered their inhibitions, leading to actions they may not have considered otherwise.

6. Peer Pressure or Social Context: Sometimes, the social environment or pressure from others can lead to actions that might not align with someone’s true feelings.

If this situation has made you uncomfortable or confused, it might be helpful to have an open and honest conversation with your friend. Discussing your feelings and clarifying intentions can often prevent misunderstandings and help maintain the friendship. It's important to consider how you feel and what you want from the relationship moving forward.
