Dear John,

The feelings you're experiencing are quite understandable, and I commend your desire to examine your feelings and the situation more closely, rather than flying off the handle.That shows a great deal of maturity.

Why do some girls only hang out with guys? Being male, I cannot give you a definitive answer, but I'll bet it's for the same reason that some guys mostly hang out with girls: they find members of their own sex inaccessible, and find they get along more easily with the opposite sex.

Girls Are Catty

Girls are encouraged by societal stereotypes to be catty.

Girls of high school and college age can be very socially competitive and very catty (depending on what groups
predominate in the environment).

In that situation, it may be tough for her to find close girl friends, especially if your girlfriend is the kind of person whose qualities are envied by her peers.

She may seek male friendships, because there's no competition, no fear of backstabbing, and she may feel
she's more appreciated for the person she is, instead of being the target of jealousy. (Am I right, ladies?)

So, should you be worried about it? Yes and no. It depends on how you play your cards.

You've Only Been Dating For A Month

I agree. He has to remember, they don't know each other that well.

First off, you've only been dating a month, and it's highly likely this new living situation has been in the planning stages long before the two of you started dating.

She's Not Trying To Hide

So, don't take it personally. It's not like she's trying to hide this situation from you, and in fact, it sounds like she invites you to hang out with them.

This means that she wants you to be comfortable with the situation, and that she has nothing to hide.

Be A Good Boyfriend

But, this is all contingent upon you being a good boyfriend. Give her the attention, the care, and the personal freedom she deserves, and she will not need to seek romantic attention elsewhere. Blow her off, treat her with insensitivity, and you may find that consolation from her roommates turns into something more. So, as long as you treat her
well, you have nothing to fear.

But, you also have to relax. If you allow yourself to be so consumed with needless worry that you close yourself off, that can be a put-off to your girlfriend.

Get To Know the Guys

In fact, the best thing you can do is get to know these guys, even become their friends. A friend is less likely to try to usurp your privileged position.

You can choose your friends, and you can choose your girlfriends, but you cannot choose your girlfriends' friends.
