I have one for you all today ... how to know if he is interested in a relationship?

And I mean ... you've had sex, you have been dating for a while, speaking regularly, texting, messaging on Facebook etc - but is he interested in a relationship?

At what stage do you ask? How do you approach him?

More importantly, how do you know if he's wasting your time?

That depends - how long have you guys been seeing each other? Has his behavior changed after you had sex? Is he more attentive or less? does he communicate more or less ever since? Did you guys ever have a talk about what you're looking for? A lot of people are just insecure when it comes to new dating situations. I'm always a firm believer in trusting actions over words. If a guy sleeps with you and then acts a little less enthusiastic, I'm inclined to say he doesn't look for anything serious. If he does act more enthusiastic (communicates more with you, is more open in regards to sharing things/thoughts with you, is more affectionate) then I'd see this as a sign of interest in a relationship.
