Family issues..

Ma

I got into an argument with my moms sister because she seems to think I am mistreating my mother by telling her the truth about her childish actions and decisions she's made in an abusive relationship. I haven't spoken to my moms sister in a couple years but she insisted on messaging me on Facebook to give me a dose of what she thought of me. She called me a babykiller because I had an abortion back in 2013. I have since asked God to forgive me and bless me when he saw fit which he has as I'm 19 weeks pregnant with my Angel from above! By the way, my moms sister can't have children as she has tried for mamy years she's in her 40's now. She is a person who has a lot of anger inside and usually very highly tense. She has never been pregnant and I feel she's now jealous that I have conceived again after my hard decision with the first. What should I do?
