A friend of mine has been dating a guy for three weeks. They hang out a few times each week and are sleeping together, yet they’re not “friends” on Facebook. My friend thinks this is weird. It’s not as though he doesn’t use Facebook. In fact, when she was last at his apartment, he was on the website and showed her photos from his friend’s wedding. Conversely, I am “friends” with guys I went out with or kissed once, and now I’m not sure what to do about them. Do I de-friend them? Do I restrict their access to my profile? The online world makes things so confusing.
