You might be over reacting because it is an ad that pops up on the email.... I get ads all the time on my gmail account about single guys interested in my area - I ignore the ads I also get other advertisements too and I pretty much ignore that too. I don't believe your husband solicited this info that is coming I know I didn't. Now if you say your husband got an email from a single girl then there are issues.. But he probably did not solicit this ad that came across his email screen.
