Early in my pregnancy... my boy friend mom said she will not help us if we keep baby?

we moved from NY to FL he transfered his job i couldnt , im currently not working. my bf have to work double shift like every day even on his day off. i havent spoke to his mom since she said dat, he had told her that we will keep the baby. its been like 3 mth since she said that, she called me the other day but i didnt answer, i called her back the next day she did not answer. when or if she call back should i be rude or dont answer back.
