Okay so yesterday I got a message off someone who made a fake instagram account to text me anonymously to tell me that my boyfriend had been cheating on me with another girl. Luckily he was sitting next to me when this message came through and didn't react angrily or lash out he cried to me and simply tried to bee me to not believe it and swore that he did not do it. I text the girl that he supposedly "cheated" on me with and she told me that it 100% did not happen. I'm really not sure what to believe I need advice.
