I'm going to ignore my pregnant friend
Why would you ignore her?
She is totally annoying and I can't be seen with her anymore.
She is going through a tough time and might not be herself. You should be more patient with her.
I don't care.  She should learn to deal with my rejection.
I can understand why you want your friend to be more independent, but remember that this is a difficult time for her, and it is only temporary.  She is having trouble coping with the physical and emotional difficulties of pregnancy, so even if you can't help her, at least let her know gently.
