I think that happens if you let it. I know people who are living alone who are still tremendously social, because their default answer when a friend asks “hey, do you want to come out and do X?” is “yes”. That's what makes the difference.
So I think you can be less social and more bored, but you can just as easily use it to become more of those things, by socializing with more people more often instead of a single room mate more often than not. It also depends on what you mean by social. For example, you can probably explore sexual interests more easily if you're living alone.
Basically, you remove any forced social interactions by living alone. You have to build and find them for yourself.
I typically become less social when in a relationship. When living alone I'll jump at the chance to go out with friends, but in a relationship it seems far less appealing to go out.
The question is whether that's less social. Maybe less externally social, but if that's the case it seems like it's because your significant other is fulfilling your need for social interaction. I don't think there's anything wrong with that, really.
This is exactly right. I actually became more social when I got married, but not because I'm going out anywhere, just I now have a built-in, zero friction way to be social.
