I have a myspace, but I do not get on as much as I did in my prepubescent days.

I think it could break up a relationship. For example, I wouldn't date a girl if I think she gets on myspace too much; same with texting, facebook, and other things. I am sure there are other ways it could destroy a relationship, but if you don't like myspace, or people that abuse it, you have nothing to worry about.
