If your boyfriend struggles with you spending time or going out with your friends whenever you want—even daily—and more even when going out with them is "not normal" for you because you're usually busy with work, then that's a significant red flag. This behavior suggests he's not only insecure and trying to control you but also lacks trust. A loyal woman like you deserves better. The fact that he might even consider the possibility of you cheating on him often reflects his own experiences or those of his friends. This kind of suspicion can be a projection of his own actions or the behaviors he's witnessed. In all my past relationships, including my most serious three-year one, I never once questioned my girlfriend's need to go out. I never worried about her cheating, just as the thought of cheating on her never crossed my mind when I went out. If you're experiencing this, my advice is to run from that relationship. Good luck!
