Infidelity or dishonesty can be complex issues that stem from various underlying factors. However, I can offer some general possibilities:
Fear of judgment: He may have lied because he thought you would disapprove of him going to a massage parlour, especially if it's known for offering services that go beyond a regular massage.
Guilt or shame: If he felt guilty about going to the massage parlour, he might have tried to hide it from you to avoid confrontation or negative feelings.
Desire for privacy: He might have wanted to keep certain activities private, even if they were harmless, thinking that he deserves some personal space.
Issues within the relationship: It's possible that there are underlying issues within your marriage that are leading to dishonesty or a breakdown in communication.
Peer pressure: He may have gone along with his friends' plans without thinking through the consequences of lying about it.
It's important to communicate openly and honestly with your husband about your feelings and concerns. If you discover that there are deeper issues in your relationship, seeking couples counseling or professional help might be beneficial.
Ultimately, the best approach is to have a non-confrontational conversation with your husband about what happened. Express your feelings calmly and ask him to explain why he made that decision. Effective communication can help build trust and resolve any underlying issues in the relationship.
