Lately, well the past month my sister been acting like she hates me. Every little thing I do sets her off. I try so hard to watch what i say. We used to be so close, I feel like my pregnancy is drawing us apart. I really don't know what to do.. she tells me my face isn't pregnant and always choses her friend over me. I don't like her friend cause she keeps dating my ex(S). What can I do? I tried talking to her and nothing seems to be helping us.. advice please? She's 16 btw and I'm 18.
