I have a girlfriend that I love. I was her first sexual partner, but she had two ex-boyfriends before me. One time, I saw her texting someone and calling him ‘sweetheart.’ I told her not to chat with him again. After that, she sent me an animation about cheating on Instagram and said it was just for fun. Recently, I saw her talking with one of her ex-boyfriends about work-related stuff. Her other ex also texts her, but she told me she is not talking to him. She even told me herself that she is talking with one ex and ignoring the other, which makes me feel like she wants me to be insecure. We are in a long-distance relationship. Should I break up with her or not? What do you advise? Should I talk to her or just ghost her?
