Today's rant: Clingy Boyfriends/Girlfriends

First of all, I am a girlfriend. I am also NOT a clingy one.

I know that when you have a significant other, you want to spend every waking minute of the day with them. But there is such a thing as taking it too far!

Today's rant is brought to you by frustration at my roommates.

A little bit of backstory:
I live in an apartment in a college town with my boyfriend and another couple. If we weren't all poor college students, I doubt we would all be living together. My boyfriend and the other male in the apartment have been friends for years, and when we all ended up going to the same college, we all decided to save money by moving in together.

The thing is, neither of them are bad people. They're just....kind of lame. And by kind of, I mean they're really lame.
Anyways, my boyfriend will occasionally ask the male half of our roommate-couple if he wants to go out and grab a beer, or spend a few dollars at a local retro arcade. The problem is that 3/4ths of the time, the roommate will then turn and ask his girlfriend if she wants to come, even if she wasn't invited! It's pretty lame.

Today's reason for annoyance, however, is because of the female half of the relationship. My S.O. asked our male roommate if he wanted to go out and get a beer at a local bar that had some drink specials, and our roommate said sure! I made it pretty clear that I was not going, and my boyfriend clearly asked only the other man of the apartment.
However, when our roommates were left alone, we could hear the following exchange:

girl roomie: "So should I come out, too? Can I come with?"
male roomie: "I don't think Mae(<--me)'s going..."
girl roomie: "So you're just going to leave me here, like some jerk?"*
(*note that this was not a fun, sarcastic voice, but a super-guilt-trip tone)

She continued to guilt trip him for a little while after this, too. He did manage to stand up to the pressure and went out with my bf, but really?!

People need to go out with their friends sometimes. If you aren't invited, don't push it! I actually LIKE when my boyfriend goes out with his friends since we don't share all of the same interests, and I'm sure he loves to be able to talk to someone who DOES share those interests. I know that I like to go out with just my girlfriends sometimes, and I definitely do not want to be guilt-tripped about it.
