Sometimes my gf tells me about things people say to her or do. Most of the time it's about a guy pissing her off, saying something mean to her or even how this one weird guy started talking to her.

How am I suppose to respond? Usually I just go okay or ask for further clarification but that just leads to her thinking I'm jealous or some shit. Like one time I asked, is this a friend or maybe the guy is interested or something. Idk
