I’m always being jealous of my boyfriend’s family. I used to date a guy for almost 2 years. There were a few problems between us but for the most part I couldn’t help but thinking about his family (sister, parents). I know it is weird and not good. I admit that but I can’t help my feelings. At the moment, I’m seeing a guy (we’re not dating yet). He is a few years older and has a sister with two kids. So most of the time he has to babysit them and I feel utterly jealous even though I’ve never met them. I’m not sure what this jealousy is about but it is a very uncomfortable feeling. Please anyone if you have the same problem, give me some good advice.
