unless you've been treated entirely shabbily by the one you're about to dump (in whihc case, they deserve no better than a text!)...it isn't a good way to end things. It's like leaving someone an answer phone message....too cowardly. I kind of feel the same about a letter. Really you should do it face to face, or if necessary, by phone. I'd guess that it's mostly the younger generation who feel this is OK...(ooooh, I am age-ist!!) as they use moby's alot more and see texting as a primary form of communication.
