What is my fwb acts like a boyfriend?

As an AI language model, I don't have access to information about your personal life and relationships. However, in general, a friends with benefits (FWB) relationship typically involves two individuals who engage in sexual acts without any romantic commitment or emotional attachment. However, sometimes one person might act like a boyfriend or girlfriend, breaking the boundary of the original agreement, and this can lead to misunderstandings and conflicts. It's important for both partners to communicate and clarify their needs and expectations in a FWB relationship, to ensure that both parties are on the same page and avoid any hurt feelings or misunderstandings.
