UPDATE (What Should I do?)

So I caved. I told my friend about my brother...Guess what happened? This trick told me that I was lying and she thinks that I'm just jealous. She said that I had been "hating" on her hooking up with my brother before he even came to visit. (mind you she used a number of curse words and invectives while saying this to me) Can you imagine the look on my face when she was saying this? I ended up having to laugh; because that was all I could do to keep from slapping her pregnant ass! And I'm not a violent person. That just isn't me...Wasn't raised like that...Fighting is primitive and to my credit, I have never been in a physical altercation in all my days on this Earth and I don't plan to ever be...Anyway; after cursing me out, she told me that she was going to tell my brother the "joyous" news and that there was nothing that I could do about it. I said "I didn't tell you all of that in hopes that you would refrain from telling him, you little Jezebel! I told you so that you could brace yourself for his reaction, which I assure you will be derived from the things you don't know about his actual life!"
She wasn't trying to hear me though. It is always so funny to me when I try to warn these broads about my brother and they don't believe me because they think that I'm suffering from sort form of sibling rivalry. worse is when they think I'm telling them because I'm jealous of the fornication infested facade that they have going with him. To that I say "Oh fuckin' Please!" I could expostulate further but it's not worth it...Anyway I have washed my hands of the situation...Two tears in a bucket, fuck it, fuck her and four people who look like her!

What Should I Do?

What Should I Do? Okay here's the thing, I have an older brother. He's not that much older than I am. There is a yr and 9 month age difference between us. Because we are so close in age, we hang out a lot when I'm visiting the westcoast (he lives in LA)...In fact he and I have always been close. We went to the same schools for most of our lives and have a ton of mutual friends...Anyway my brother is what women consider to be fine, hot, attractive, charismatic, sexy, etc... (I don't see it lol) but anyway my closest girlfriends all have or have had a thing for him at some point or another and he has fucked ALL of them! As you can imagine, his rendevous with my friends have created some problems for me over the years. Anyway as the years progressed (he conquered/ had his fill of my girls) but when I moved to New York for college (and my girls went to other states to do the same) those types of problems subsided...Since then all has been well within my circle of friends....BUT last month my brother came to Brooklyn to pay me a visit...While he was here he met and had sex with another good friend of mine. I went to college/ shared a few classes with this particular female and I've come to value her place in my life over the past 4 1/2 yrs that I've known her...Anyway the problem is she got pregnant...My brother went back to LA...he doesn't know yet; and considering the fact that he is ENGAGED to a lovely young lady back in California AND he has a child with her!! I don't think he is going to want to know...Hell, I don't want to know what I know. My friend here in NY has no idea that my brother is in a relationship back in Cali. She is aware that he had a child but my brother mislead her...She thinks he is single. What should I do? I don't want to not be loyal to my brother by blowing up his spot; but at the same time I don't want my girlfriend to be in this situation blind; which she is at this point. My friend asked me not to tell my brother the news, as she wants to be the one to break it to him. She only told me because she wanted to know how I thought he'd react when she told him. (can you imagine what was running through my head?) This is such a mess there is no way that I'm going to come out of this without someone being upset with me; which is really fucked up because I'm not the one who was lying or cheating or having sex with anyone! I've always told my friends to stay away from my brother, to no avail...It was kind of funny and cute when we were younger, but now things are more serious. There are babies involved!
