My Friend is Pregnant Again

So, my friend from college is pregnant again. When she was pregnant with the first kid, her "baby daddy" all of a sudden announced he wanted to become a woman. Then after she popped out the kid, she went kind of postpartum crazy. She quit her job, became a stay at home mom (even though she's single), she can barely afford to keep the house she lives in and has become a recluse. She literally disappeared from the world with her baby for half a year.

Then, Bam! She should up one night when we were all going out. She tore one all, picked up a guy and entered her "promiscuous" phase (Which she is still in.) She picked up a guy and went home with him that night. This is a girl who had only slept with 2 guys before having her first kid. Then, she goes on a tear. Within 3 months, she is pregnant again and has no idea which guy is the father. Here we go again!

You can probably guess what happened. The three guys who could have been the daddy all ditched her. One didn't live here and was just passing through. He claimed it couldn't be him and she never heard from him again. The other two both moved and didn't give her a number, address or anything. This time, she went crazy before the baby was born. She dealt with her pregnancy by deciding to take naked pics of her self and posting them on Reddit, tumblr and other websites. She even made a couple of videos that were posted on some adult website when she was 7 months pregnant. When she wasn't satisfying guy's desires, she was sitting on a couch in front of her TV playing Video Games! She had never played a video game in her life and then all of a sudden she was playing Battlefield, Call of Duty and any other game she could get her hands on.

Fast forward to the present. Now she is pregnant again (#3) just 9 months after having her last kid. This time, the father is kind of in the picture. He is someone that she's been on again off again with since she was in high school. The guy went to high school with me and is a real asshole. He slept around, hit women, and was pretty much a worthless piece of shit! They have no future together. Neither one currently works. Hell, She hasn't worked for two years and he has been unemployed for 9 months and isn't looking for a job. He lives in a shitty house with 4 other guys and she is moving in with him this weekend. I know for a fact that he has been cheating on her and I even told her, but she doesn't believe me. I know they will probably never get married and he is going to ditch her and her kids.

And now, the frosting on the cake. They have asked me to be the Godfather for not just this baby, but her previous two kids. She is a great friend, but she is so full of drama! How can I tell her I don't want to be the Godfather to her kids and not piss her off? UGH!!!
