It's challenging to determine the specific reason why your guy friend has become touchy-feely without more context, as there could be various factors contributing to his behavior. However, I can provide some common reasons why someone might engage in such behavior:
Comfort and familiarity: Physical touch can be a way for people to express closeness and familiarity with someone they feel comfortable around, especially in close friendships.
Affection and care: Touch can also be a way for your friend to show affection and care for you as a friend. It could be his way of expressing warmth and emotional connection.
Social and cultural norms: Some cultures or social circles might have different norms regarding physical touch among friends. It's possible that he comes from a background where such behavior is more common or acceptable.
Seeking emotional support: Physical touch can be a form of seeking comfort and emotional support, especially during challenging times or after a breakup, as you mentioned in your previous question.
Flirting or romantic interest: Although you mentioned it's not sexual, it's worth considering if his touchy behavior might be a subtle form of flirting or romantic interest. Sometimes, people may not be fully aware of their own feelings or intentions.
Changes in friendship dynamics: Perhaps there have been changes in your friendship dynamics that have led him to express his emotions through touch. These changes could be related to your relationship evolving or external factors affecting his behavior.
Individual personality traits: Some people are naturally more physically affectionate than others, and it might be a part of his personality to express himself through touch.
Regardless of the reasons, it's crucial to address any discomfort you feel with his behavior. If you are not comfortable with his touchiness, consider having an open and honest conversation with him about it. Share your feelings and boundaries in a non-confrontational manner. Communication is essential in any friendship, and addressing the issue directly can help maintain a healthy and respectful relationship.
