<human>: My boyfriend and I have been together for a year and a half. Yesterday we went shopping together. He ran into one of his old buddies so he went to go say hello. I start following him then immediately notice that I knew the guy. We didn't date or anything, but we used to see each other before my boyfriend and I started dating. Anyways, after they were done talking my boyfriend realized that the guy remembered my name. I was in a weird awkward mood after all that and just came out and told him that we used to see each other. All my boyfriend said was "I really wish you wouldn't have told me that." It wasn't til later on that I started feeling really bad because that's definitely not something that I would want to know about my boyfriend either. He wasn't mad, but he was understandably in a bad mood and still is today. I know I should've kept my mouth shut, but that's not what happened. Anyways, I've tried to talk to him and tell him that it was a long time ago and how much I love him. He's the best thing that's ever happened to me and I hate seeing him like this. He doesn't wanna talk about it which is understandable. What can I do to make him feel better? I don't know what to do. :/

Can you provide a brief overview of the text?
<bot>: My boyfriend and I ran into his old friend which happened to be someone I used to see, I told him about it and now he's in a funk and I don't know how to get him out of it.
