How to establish boundaries with my partner
My fiancé (39M) and I (35F) have been together for just over five years, and we have a strong relationship. We’re set to get married this June. However, something has come up recently that has intensified my anxiety, and I can’t seem to shake it. We both work for the same company, though we don’t interact during the day. Recently, a new girl was hired to fill my fiancé’s old role, and he has been tasked with her training. From the start, I felt an odd instinct about her, influenced by her outgoing personality and her social media presence, which includes many provocative and revealing photos. She’s only 23. Since she joined the team, I’ve noticed my fiancé frequently brings her up in conversation—what she had for lunch, something funny she said, and so on. It’s starting to irritate me. I’ve also caught them texting late into the night after work. One day, feeling particularly anxious, I looked through his texts on his laptop. Most of the messages were work-related, but there were definitely some flirty comments mixed in. She referred to him as "Thanks papa," called him dreamy-eyed, and sent him playful memes at night. There was even a time she called him in tears, upset about a work-related issue. Additionally, he recently followed her on Instagram despite claiming he rarely uses the app and doesn’t follow any other coworkers. (I found that out while snooping, which I regret.) I’m unsure how to discuss my discomfort with him, especially considering the way I discovered this information. I want to explain my feelings without admitting that I looked through his messages. I don’t believe he’s cheating, but I’m concerned it could lead to emotional infidelity or that he might be attracted to her. He even mentioned wanting to switch gyms to one that she attends, which he brought up casually. How should I approach this situation? **TL;DR:** I'm anxious about my fiancé's new coworker and unsure how to bring up my concerns.
