She has a job and there were multiple rumours of her flirting with somebody at this job. Then she starts messaging him and I asked to see the messages and she was extremely hesitant to show me. She eventually did and the conversation was normal. Then I scrolled up saw that he sent kisses and she snatched her phone of me. To me levelheaded this is a huge red flag. She persisted I have nothing to worry about but my reasoning was if I have nothing to worry about show me the messages and agin she refused. I feel like I’m stuck between a rock and a hard place and I don’t like how this situation is making me out to be. I feel like I need to know but at the same time feel like I’m being controlling and I seriously don’t know what to do. There’s more to it but that’s the main reason I need advice.
