If a guy hasn't texted me in a week, should I give up?

Anonymous
He messaged me on a dating website at the very end of last month.

We exchange numbers after a week of lengthy messages. We Skyped for three hours with each other that next week . We texted almost every other day or every day for the past few weeks. We even planned a date which is supposed to be next Friday.

I hadn't heard from him since last week when we were texting that night all of the sudden he stopped responding and I tried getting back to him a day later and still nothing. I was on the website again the 2 days after I texted him and I noticed that his account was gone.

A guy friend of mine told me that it was a lost cause.
