My girlfriend told me she had an affair with a married man before we met?

I've been dating my girlfriend for 5 months. We talked about past relationships about a month in. I knew the man in question as her ex-boyfriend, who was "old enough to be her father." She also told me they were still good friends. I didn't have a problem with this.

Today, she mentioned an email from him this morning, that he was on vacation with his wife and she was glad he was happy with her again. I said I had assumed he was divorced and asked if they were just separated when they were together (over a year). She said no, they had "an affair type thing."

I was a bit shocked and asked what that was like. She just said she didn't regret it, but knew it wouldn't have worked out. She then said she didn't want to talk about it.

Well, I'm a little concerned, obviously. She has said she believes in monogamy, and I guess she wasn't doing the cheating, but still. Her lack of regret also worries me...what if their marriage was ruined?

Also, why does she still talk to him? Isn't that incredibly disrespectful to his wife, even if they have broken up?

Finally, shouldn't she have told me this before? She didn't really tell me now, just casually brought up the guy's wife in conversation.

Looking for opinions/advice. What should I say, if anything? Is her previous affair any of my business?

Thanks.

I'm not especially worried that she will get back with this guy. When I say old enough to be her father, I'm talkin' the guy is retired. His children are older than she is. There isn't a future there. She isn't after money either, her family is very well off. It was a vulnerable time for her - there were circumstances.


Anyway, I'm more concerned about her character. Doesn't she care about his wife at all? I mean, I don't know all the details, but I don't think she'd like it too much.
