What do I do?

What do you do when you have a friend with such severe problems in her life you almost want to turn your head and have no part in it?

There's a girl who lives here that ever since Ella was a newborn has needed me to be her friend. The first time I met her it was I NEED YOU TO BE MY FRIEND. I'm sorry, but I should have clung to that and been there as a good friend to her. I then saw her smoking while being 9 months pregnant and lost all interest in being there for her.

I'm writing this post, because I'm struggling with something. I as a person try to please everybody. I can be there, even when I can't. I can definitely do that, but honestly I can't. I can be friends with everybody, but truthfully, I'm so busy I hardly have time for my work and family.

This girl has once again entered my life. Our babies are now 1 1/2 and I figured it wouldn't hurt to be a friend to someone who needed one. I was on the phone with this friend yesterday and I had asked if she had the internet. Her reply was, "Well, yes and no. We don't have a DSL cable." Um... okay, a what?? I've never heard of a DSL cable. She too agreed that she'd never heard of it, and thanked me for confirming this. I asked, well, do you have a laptop or a desktop and she said laptop... but she's banned from it.

WOA! Okay... back up... you're an adult and you're banned from a laptop? What kind of a marriage is this girl in???? She then starts opening up and trying to in not so many words tell me how miserable her life is, when I hear "GET OVER HERE!!!!!!!!!" and that was screaming from her husband. She said she had to go and got off the phone.

I don't know what to do. I hate to turn my head and walk away, but I just don't think I can handle another situation in somebody else's life. I know she needs a friend, but I don't think I can sit here and watch a friend go through a life like that. I doubt she'll leave him, she's a very insecure person who has a bad outlook on herself. I'm completely opposite from this and can't understand why somebody would allow their lives to get to this point.

I guess I kinda need advice on what I should do. I have a lot on my plate and can't take on another person's problems, but what kind of person does that make me?
