My girlfriend and I have been dating for four years now. She has started to text a guy she meet through one of her guy friends a lot. I looked in her phone and there were a lot of text messages from him and how they should get lunch sometime. But when I confronted her about it but she said they're just friends, so I looked at her phone and she deleted all of his messages. What do I do? She goes to school an hour away and comes home on the weekends. I've tried to talk to her about it but she just keeps saying there just friends. I've tried to be honest with her and tell her how I feel but I feel like I may be acting to jealous. I also am afraid to tell her how I really feel because its happend in the past and I don't want to get mad. What do I do?... Please help
