When your male friend says, "I don't trust myself around you," it suggests that he might be concerned about the potential for romantic or intimate feelings developing between you two if he stays at your place. By saying this, he is acknowledging that he doesn't feel entirely comfortable with the idea of being in such close proximity to you for an extended period.
It's important to consider the context of your friendship and any previous interactions you've had. If there have been moments of emotional or romantic tension in the past, he might be worried that spending time together in such an intimate setting could complicate your friendship further.
His statement could also indicate that he doesn't want to impose on your hospitality or create any awkward situations that might arise from living in close quarters.
In any case, it's essential to respect his feelings and boundaries. If he feels uncomfortable staying at your place, it's best to honor his decision and not push the issue. You can reassure him that you understand and that he's welcome to reach out if he ever needs help or support in the future, even if it's not with a place to stay.
It might also be a good idea to have an open and honest conversation with him about his concerns and your feelings, especially if you value your friendship and want to maintain a clear understanding of each other's boundaries. Communication is key in any relationship, and being open about your intentions and emotions can help prevent misunderstandings and strengthen your friendship.
