I appreciate the distress you feel, but I am confused. You say she is your girlfriend, but then explain that you argue regularly about her behavior, you don’t go on dates, she prefers her video friends over you, she is secretive, and you are constantly worried that she is unfaithful. This doesn’t sound like you having a healthy, loving relationship. She sounds more like a source of frustration rather than a source of reciprocal love. I would stop looking for something from someone who doesn’t appear that interested in giving it. Perhaps it is time to find a real rather than virtual girlfriend.
