Is it more than just a friendship? My girlfriend and I have been together for about a year and a half. In the beginning my girlfriend was very honest with me about her past relationships. She told me that she and her ex were in a really messed up relationship for 8 years. Now they are just best friends. I have met my girlfriend’s best friend and spent time with the both of them. I still think they sometimes cross the line. I try to relate it with me and my friends but I never dated any of my friends. I have tried talking to her about it and we have fought over and over again. She says I am insecure and have nothing to worry about. I can’t help but think that there might still be feelings between the two of them. I get sick when I think of them alone. What should I do?
