Hey, I don't really know where to start. My husband and I have been together for almost 7 years now and married for almost 1 year. There have often been things in our relationship that made me insecure, as it is my first relationship and he has had several ex-girlfriends. The main reason I'm writing is actually that he is currently finishing his schooling and I am working to pay the rent. From the beginning, since he started this school, he has been talking about a girl named Lilly. She is from Canada, does sports, and so on. I never asked about her, and he kept talking about her, even how much she annoys him and how she keeps talking to him. Long story short, I didn't want him to follow her on Instagram because he doesn't follow his other classmates either, and I had a weird feeling about it. He unfollowed her and shortly after followed her again, arguing that people at school were asking him why he unfollowed her. This went back and forth for a while. A while ago, I found out that he had done something with her and kept it a secret. He said two of his friends were also there but initially denied it, for whatever reason—what should I have against it? We argued because he lied to me. Now, a while later, he told me during another argument that he was alone with her there... but apparently, nothing happened; they just talked. Then why keep lying to me for so long if nothing happened? Why didn't he say it back then? I don't know what to think. What do you all think? Sorry for my English, by the way.
