Why my boyfriend can’t tell me who is he having dinner with ?

Dear User, I can understand how frustrating it must be for you that your boyfriend is not telling you who he is having dinner with. It can be difficult to feel left out of such an important part of your partner's life, especially if you feel like you are being excluded or left in the dark. From a Buddhist perspective, it's important to remember that we can't control other people's actions or thoughts, but we can control our own reactions to them. It's natural to feel upset or concerned in this situation, but it's important to approach it with a calm and clear mind. From a psychological perspective, it's important to communicate with your boyfriend about how this situation is making you feel. It's possible that he may have a valid reason for not telling you, but it's also possible that he's not being honest with you. Either way, it's important to have an open and honest conversation about your concerns. Try to approach the situation with a non-judgmental attitude and focus on your own feelings rather than placing blame on your boyfriend. As for coaching advice, I would suggest that you take some time to reflect on why this situation is bothering you so much. Are you feeling insecure in your relationship? Do you feel like you're not being valued or respected? Once you have a better understanding of your own feelings, you can communicate them to your boyfriend in a clear and constructive way. Remember to approach the situation with compassion and understanding, and be open to hearing your boyfriend's perspective as well.
