Yeppers, she sounds pretty mixed up, it could be attention, her bf sounds like a half arsed control freak. She sounds like she needs to pick herself up, dust herself off and decide what she wants to do and move on. I sure the heck would not want his fetus growing inside of me even though I would know that it would be half mine. She sounds like she does not know what she wants and now would probably not be a good time to continue on w/the pregnancy.
Keep in mind, you cannot tell anyone what to do, you will just stress yourself out more.
I would not go to the abortion w/her if I were you, don't be silly, you have different opinions, you are pregnant and being upset will not help your pregnancy, even though I do understand, I would back off, as a friend and let her try to find herself. Don't get me wrong, I am not judging her, I am just stating my opinion, you can still be friends. A lot of pregnant females have second thoughts.
Sincerely,
sandy
