Is this bad???

I feel very jealous over my boyfriend when he talks to other girls because in the past he has lied to me and stuff like this and he had also kept things from me a lot

But if I was dating another guy I wouldn’t be jealous or anything like that over them because they haven’t lied or anything like that

Some people make me feel bad about being jealous and are like but wow u wouldn’t do that if u were with another guy and I explain my point in reasoning but they still think I’m a bad person
