Re: the need to flirt
^ Yes, that's another reason why married people (and even singles) will flirt..........to know that they "still got it"............or to know that the opposite gender still finds them attractive. It can be a way to validate your worth/ego.
Yeah, no doubt, it's flattering that someone besides your SO finds you attractive........you can't control the feelings of others. But, frequently testing the marketability of your resume when you already have a job...........can mean that you have to sit down and sort out your security issues. Cuz it might feel good to get an ego boost in the process........but it can be at the expense of other people's feelings (and that needs to b considered).
