My husband has a new coworker that I've come to feel that I'm not so comfortable with her. First time I saw her, they were leaning towards each other whispering a bit too close. I've seen way too flirty of texts between them, and suddenly they are following each their on Instagram. My husbands argument is that she's a lesbian and married. I feel like that's a cop out. Once she texted him "you called?" And I checked his call history and there wasn't one. I asked him and he said he deleted the call entry because he knew I would get weird about it.
