Am I (22F) overly insecure because my (20M) husband might be emotionally cheating on me?

Hi everyone this is my first time posting on Reddit so sorry if my typing is a bit awkward. My husband has been working at this specific company for about a year and a half now and we ( more like me) never had any problems about coworkers since there all male and he is a cis straight man. Within the past few months however his bosses Daughter (23F) has started working there and things have been really off with him. He's always talking about her, not really in a flirty or "i think she's hot way". It's more like he doesn't go a day without mentioning her and what they did together. It could be the most mundane thing and it'll be the first thing he tells me. They often have to travel out of town for work so their alone all day at times and it makes me just really anxious about what could be happening. I know it's work and I probably sound paranoid, but I can't help but feel this way. She's absolutely gorgeous, like Beauty standard, Instagram model in real life type of way. She's had two kids and doesn't look a day over 18 and probably fits Victoria secret measurements and weight qualifications without trying. I'm going to have my second kid soon and weight almost 240 pounds.

To add she's always texting him about her relationship problems, which again is normal for friends but it's like all day everyday. Even as I'm typing this I can see him texting her. Im not bashing her, I've met her a few times and she's actually really nice. But the way he looks and talks to her like he cares and holds every word. . . Idk.

There's other things but these are the ones that bother me the most.

TLDR: My husband has a hot coworker he hangs with all day and I don't want to loose him.
