When I found my cohabiting girlfriend secretly reading her ex-boyfriend's love letter?

If I were a man, I would ask her what's on her mind and tell her what she thinks. Is it my fault? Bad for her? Or something else?

If I am a woman, hehe, I may miss my old boyfriend or look at my old memories.

However, some people like to keep everything their former friends gave them. After all, they have passed. It doesn't matter if you look at them. Who hasn't had a first love? Who hasn't had memories? It's okay to have some fun when you're bored. You just need to remember to tell him what you think, such as being jealous. . . Wait, since we are together, we should open our hearts to each other and say.
