My boyfriend's parents is coming in couple weeks and its not that i don't want them here but they are really against of everything, that is why we didn't tell them i am pregnant, because my boyfriend knows they are just gonna say some stupid. I am worried about my baby. I don't even get it why they have to say something if they are not even giving us money to support us. My boyfriend just telling me not to care what they will say, but its just irritating me and making me stressful.
