My partner manages a team at work, mainly females and he gets on naturally well with females but always makes it clear he doesn’t mix work with personal life. I saw a message on his phone from a girl at 2am a few weeks ago. It turns out it’s a girl from work he employed over a month ago. They have been messaging daily - long detailed texts with lots of emojis, never work related . He just says she a really good friend. I have explained I am not comfortable with him texting her outside of work hours - he didn’t see there is a problem but said he would talk to her to stop. I recently found more messages. He is still texting her every day and in the evenings when I am out with my friends. I just don’t know if I trust his intentions? He is telling her I am out and that’s he is free and she should call. I don’t know why he feels the need to text her so much and why? Especially as she is his employee. I am worried he is giving off the wrong impression or acting like an emotional support for her? Also why is he so invested in getting to know her? If anyone else has any similar experiences much appreciated.
