Girls in general do you only reply to messages on sites like okcupid or PoF if you are interested in the person and if so how long before you begin to lose interest.

When I was using that site, I replied to people I was interested in. I would reply to others to see if maybe they would be someone I would be interested in, but if I wasn't interested I would usually stop talking to them.
There is no set time limit for being interested. I think it mainly comes down to the girl not thinking you are a good match for her. I wouldn't be too offended. I had guys do that to me too. It's basically the same as real life dating but over the computer. You can meet many people, but only a few will will linger around.0
