There's a suitor to my girlfriend, and they've been in contact. She plays mobile game with him, and sometimes she lies to me that she's sleeping but she's actually playing mobile game with him. I don't feel good

Dear friend, I can sense that you are feeling uneasy and hurt by the situation with your girlfriend and her suitor. It's understandable that you would feel this way, and it's important to take care of your emotions during this time. It's natural to experience jealousy and insecurity when we feel like our relationship is being threatened. However, it's important to approach this situation with mindfulness and compassion for yourself and your girlfriend. From a Buddhist perspective, jealousy and attachment are seen as obstacles to our inner peace and happiness. It's important to cultivate a sense of detachment and non-attachment to our relationships, recognizing that they are impermanent and subject to change. The practice of loving-kindness and compassion towards ourselves and others can help us to let go of negative emotions and cultivate positive feelings towards ourselves and others. From a psychological perspective, it's important to communicate openly and honestly with your girlfriend about how you are feeling. It's possible that she may not realize how her actions are impacting you, and communication can help to clear up misunderstandings and strengthen your relationship. It's also important to set boundaries around what is acceptable behavior in your relationship, and to honor those boundaries with respect and trust. In terms of coaching advice, I would suggest having a conversation with your girlfriend about your feelings and concerns. Share your feelings in a non-judgmental way and listen to her perspective as well. Try to come up with a solution that works for both of you, such as setting boundaries around communication with other people or scheduling time for just the two of you. Remember to practice self-care and self-compassion during this time, and to seek support from friends or a therapist if needed.
