My boyfriend and I got into an argument over this... So my boyfriend added this guy to fb. So I asked who it was and he said his ex. So I got jealous and was mad at him mostly for not telling me and kinda mad cus I was jealous he was talking to his ex. He got all mad at me for being jealous and said it meant I did not trust him. And I got mad that he got mad at me for being jealous. I wanted him to be understanding instead of telling me to just "stop being jealous." He said that nobody is jealous over stuff like that. I'm mostly hurt because of the way he reacted to it... makes me feel like he doesn't care that it makes me feel that way. But please let me know what you think.
