My friend might be pregnant and is making bad choices, what should i do?

she is smoking weed and is cutting her classes. she ditches all her friends for her boyfriend (and she doesn't care for him at all)when we have all been there for her. She refuses to change no matter how many times I and another friend have told her to be careful. Others that she hangs out with dont tell her to stop smoking weed or cut classes and have unprotected sex besides me and the one other. She says horrible things like: ';I'll just kill it with the weed'; and ';F*** it'; and says that I am a horrible friend. I know that I can't change her unless she is willing to change, but I really need help....I love her dearly, but she acts like all the 7 years we have been 'sisters' meant nothing. She lives with me and I cook and clean up after her. I always help her when she needs it. I just found out that she might be pregnant but we don't have money to find out. If she keep smoking weed and what not, she could seriously hurt the baby. I just want my old friend back.

kick her out of the house, tough love...shell learn real fast.My friend might be pregnant and is making bad choices, what should i do?
your friend is really stupid, i think you should kick her out, i know it seems mean but she is planning to kill her baby and she will treat everyone like dirt if you let her, she needs teaching properly and you said she had a boyfriend so maybe he should try living with her for a change
first off, if she thinks that smoking weed will be fatal to her baby shes mistaken...it is highly unlikely it would be fatal BUT it can cause serious side effects...your friend is extremely irresponsible and she isnt gonna change if she dosent want to...if this bothers you as bad as you say id cut her out of your life and be done with her...im sorry but i couldnt sit back and watch a so called friend of mine be abusive to her unborn baby...
honestly... i would kick her out of the house. but im more a tough love type of person anyway. i would say at the very least dont let her push you around so much. she knows you love her, but she does not feel worthy of that love. question is why do you feel that you have to prove to her that you care about her, when you already have countless times in the past and she obviously isnt reacting to it very well. do something different. think about that for a minute than i promise you will find the answer you are looking for yourself.
kick her to the curb. Or show her someone who went in the same path she is going. Someone who lives in the projects and has 3 kids at a very young age and lives on welfare. And scare her by saying that's what she will end up like.
How old is this girl? If she's a minor, I would tell her parents and make her move back in with them (or at the very least, out of your house). I know that she would probably be very angry with you for telling her parents, but it sounds like this girl needs more help than you can give her. She's acting out for some reason (which also leads me to think that she's a minor) and I hope that her parents will be in a better position to help her deal with whatever she's going through. If sh'e not a minor, there's not much that you can do other than ask her to leave your house if she doesn't change her ways (and then stick to that). Beyond that, all you can really do is try to get her to talk about why she's been behaving like that. From what you're describing, she sounds like a very unhappy person. If you can get her to tell you about the source of her unhappiness, you may be able to help her work through it, but other than that there's probably not a whole lot that you can do. Regardless, I would get her out of your house unless she's willing to do an about face. You may not be able to change her, but you don't have to sit back and watch her self destruct. Also, hopefully this will help her understand that there are consequences for her bad behavior. Good luck to you!
There isn't much you can do for her unless she is willing to change. The best you can do is sit her down, have a serious heart-to-heart with her, and help her see that you care about her and you want to see her make good choices and take care of herself. If she isn't willing to listen to you, it might be time for you to cut your losses, move out, and let her make her own mistakes. If she's that into drugs, it's only a matter of time before you get in trouble by association, and you don't need or want that.
