You don't talk about someone you're seeing to someone that you're in love with, nor should you be with someone that you're not in love with. Seriously, get your head on straight, and start using it for a change. You couldn't have possibly drank this much fluoride.

Watch Gossip Girl, you’ll get some pointers from Chuck and Blair.

"Hey, I'm totes married now, but it's lame, so if you want to ravage me..."

It's very difficult, but the other way is even more so. But if your plan is to talk about this person in order to guage the jealousy or interest of the one you really love, well then, you are a coward.

At the least let the one you love know without reference to anyone else. Having been in a similar situation I don't give this advice easily. I just know that if you avoid it, you'll pay.

If you're not with the person you're in love with, or if you're with someone that is not in love with you.. then your relationship is comparable to that of a John, and a prostitute. And the person that you do claim to be in love with, most certainly doesn't need, and most likely wound not care to hear about it.
They probably already understand the dynamics of your rather reprehensible and pathetic relationship. You won't be gaining any kind of absolution or respect from them by speaking to them about it if that's what you're hoping to achieve. If you want to achieve that, you'll just have to stop using people, and stop allowing yourself to be used by people whether that be for money or sex, or both.
Of course you maybe just looking to speak to them about it to see if you can hurt them, make them feel all jealous and insecure, but they'll likely see through all that, and you just end up making more of an ass of yourself.

Maybe just don't? What are the benefits?

The way the question is posed is almost like something you'd hear in an infomercial.

Try saying it to yourself first.

"If you can't be with the one you love, love the one you're with."
