I am pro-choice but I personaly would have too much guilt to go through an abortion. Does she want the baby? How old is she? Sometimes abortions are the right decision. Sometimes not. It's a super tough decision for a woman to make.
As for her asking your advice and taking away from your school concentration, that's not good. You need to finish school with good marks. Try your best to not be there all the time and maybe get away to study or do school work.
I posted about a friend of mine who just had a child with her BF but she wanted to leave him. Well she did leave him but now it's a HUGE mess. For a while I was getting super long emails and phone calls from her everyday. I wanted to be a supportive friend but after a while it stressed me out WAY too much so I had to take a break from her. There's only so much stress you can see before you feel as stressed as she does!!!! Despite her BF being a huge jerk, it looks like she's going to go back to him. I cannot talk sense into this chick if my life depended on it!!!!
