I know this sounds ridiculous.. I was sitting with him as he was going thru his email the other day and he had a email from someone using craigslist saying they saw his ad from a long time ago and hoped they weren't too late and blahblah.. Before he met me, he used craigslist for hookups. And a month ago he had another one of these emails and hadn't even read it, I noticed it and pointed it out and he laughed saying it's just craigslist spam. This time though, he had read it.. He hadn't responded or initiated the conversation though.

So my question is, is this something I should let upset me? Just that he read it.. Even though he didn't reply or anything. The title was RE: Saw your craigslist ad so he knew what it was before he even opened it..the last email he had had the same title, by a different person and said they were glad he liked their ad, this time it was the opposite, saying they liked his ad.. Can craigslist personals last years like that? The information I mean, or is it truly just spam because he used the personals at one point.. There are no links to other sites or attached photos..
Nothing is different, he's never home late and our sex life is amazing..when he's not working he's with me. There's no signs. 

So I ask again.. Should I be bothered by this? Is it spam from using craigslist years ago? Does craigslist spam even happen that long after posting? 

Advice would be greatly appreciated.

Edit: forgot to mention we broke up last year for a few months and I assume he used craigslist then also to find comfort at night.. So the responses may not be from 3 years ago but rather, one year.. Not meaning they were sent that long ago, but responded to.
