I have been with a boy for over a year now and currently we do not go together. We have been going through our problems but our love won't let us separate. We have a saying to see whether we are telling the truth or not. We were having a conversation and I asked him to put it on his life that he didn't talk to anyone else and he got very quiet. I began to get very upset because I figured that he was talking to another girl. He got mad at me because he said that I was jumping to conclusions just because he didn't answer me but I didn't want to hear it. I began to ask him all types of questions like who is the girl, how old is she, what's her name, and if they had sexual intercourse. He hung up on me and we began to text because he told me that he didn't want to hear my mouth. The next day while I was a school we were texting and I brought it back up again and he told me that I need to let him explain. He told me about a girl that liked him and he tole me that she recently began to try to talk to him because they were friends before he found out she liked him. He said that he told her that he didn't like her that and that he was still in an relationship. He said that he didn't put it on his life because he didn't know of the other girl was telling people that they talked and he didn't want me to get upset if she did. My question is should I believe that he is not talking to her or should I still be curious about the question.
