A genuine or accidentally-on-purpose email sent by mistake?

I'm not sure he was trying to get my attention when he was looking at and talking to her. Sometimes he is socially oblivious. I had to pull him up on his intense eye contact because I don't think he realised how unsubtle it was.

I don't know if 'jealous' is the word, but I'll openly admit that no, I didn't like the attention my DH gave this woman, and that he seemed to like her. I didn't want her to like me; I'm not interested in making friends with a woman I have nothing in common with.

For a man with no morals and no respect/love for his wife, which I'm pretty sure my DH isn't.

To be honest, I didn't suspect an affair, I was just annoyed by DH's behaviour around this woman and found it highly disrespectful and embarrassing to me. DH hadn't had the opportunity to be alone with this woman; he works from home 95% of the time, as the office is over an hour's drive away. When he did go in, there was always a group of employees, never just this woman.
DH and I go to pubs together on Friday and Saturday. There hadn't been any unusual, out of character outings by him either. I did look at his Whatsapps to this woman and it was just chit chat, him wishing her well with projects or recommending things (books, museums etc) to her he thought she'd like. Odd jokes thrown in, but nothing inappropriate.

I don't think he would want to jeopardise our (30 year) marriage and hurt me over a fling with silly young woman who he, to be honest, doesn't truly care about, but just finds pretty.

I meant physically, but I think you knew that....

He was sitting at the table on his laptop, and had been replying to emails for quite a while (he gets a lot). He didn't leave his laptop open with a particular email on for me to see.

But the rest of what you say is probably true.

I've never obsessed about my appearance, or fussed over hair or make up. I'm quite outdoorsy and sporty, as is DH, which is how we met, through a mutual interest in a sport at uni.

I've always been quite slim because of our active lifestyle, always going on walks/hikes/cycling. I've always dressed simply and practically, and never been really into clothes like some women are.

I suppose I didn't like the fact that my DH could have his head turned by the type of woman the intern is, who is nothing like me. I hoped he wouldn't like someone like that, even though I know she isn't any real threat to my marriage.

I didn't really say much to them, just 'hello, i've just come to sort out ___'. They just all got on with their work.

I didn't get an amazing level of detail from the email, but yes I did see it and was close enough to read when I walked past. And yes I did look, I couldn't resist when I saw that woman's Google profile photo.

DH used to see this woman in the office (DH works from home usually, we live quite far from his office), about once every 4-6 weeks, then last year it was often less. I had spoken to DH about his behaviour, over friendliness and staring at this employee, and asked him to think about the impression he was giving to her, last year. He knew I was not impressed at all and I think he did reign it in. I also went into the office with him several times from then on, and I sometimes did menial admin tasks he usually did when he went in, while he chatted to the blokes next door.

We're 50 and don't have any kids, but I see your point. I don't know whether he believed he actually had a chance with her; I don't think he would ever throw away our marriage. I do think he enjoyed her responding to his attention, and that it fed his ego, which irritated me.
