I somehow thought that lesbians were cool with straight women.

She is probably just overly butthurt about you letting 2 lesbians, one of which a good friend, live with you. Has she tried to live with you but you turned her down because you didn't know her long enough?

Anyways she is just a bitch and probably jealous to some extent of which you are either turning a blind eye too or are believer her lies about, combined with being a homophobe.

Dump her. Like now. And tell your lesbian friend that you did because if she finds out that your brand new GF calls her a Dyke behind her back and you don't defend her... You will lose a longtime friend just for a new prospecting relationship, with a bitch.

And it's only been 1-month at that and you've learned of a huge glaring flaw that goes against your very moral compass. Dump her ASAP before you get too involved. Bonus points if you tell your lesbian friends that you dumped her because she was insulting them and calling them dykes behind their back. You will gain much respect and lose very little.

There's no rule obviously your girlfriend is either overly jealous or dislikes homosexuals.
Of course a lot of women might have a problem with people they dont know but she doesn't have to call them fucking dykes ...

Probably pretty normal for a barefoot gal from a holler out west Tennessee way, but for an intelligent educated woman, I doubt it.

"Everyone I know has always accepted her for what she is" When it comes to this statement you can only speak for yourself and heresay is in admissible in a court of law for a good reason and SLANDER is illegal but because you are referring to a group of people the LAW lets it slide.

"My girlfriend of less than one month has an issue with two lesbians staying at my place. Even though this new girlfriend does not live with me she does spend a good deal of time there."

The immediate above quote of this post contains two "girl friends" are you Banging your girlfriend and RAPEing one of the Lesbos but question is....

Why do you have two "girlfriends" but depriving the other lesbo the right your cock has to rape her? I just dont understand... *frownz*

I would over-power and Rape Jenna Marbles you aren't alone OP...

I'd Rape this bitch its not her choice where I stick my cock when there isn't another man there to protect her. The least she could do is carry a gun.

She has issues.

Come on dude wake up. It more than the two of them being lesbians. You invited a good friend, female that you know for some time to live in you're house. No woman would like that. This is my opinion.
