I'm 8 weeks 4 days and have announced to pretty much all of my important family & my boyfriends, however I'm feeling so emotional and my grandmother, who I love dearly is not fond of the idea of me having children, it really upsets me and I really don't want to tell her myself because I feel like she's going to say something that really upsets me & I do not want to have a nervous break down in front of her lol. I have no problem talking about it it's just she has no filter and has been someone who broke my heart with words before, so I'm just gonna be really torn up if she isn't as happy as me and the rest of my family.. any advice? 😞
