Feeling some type of HATRED

THIS IS JUST A RANT AND I NEED TO RELIEVE MYSELF SO BAD... So I just found out that my EX-SIL is pregnant. I only know because she still talks to my family and her and my brother had a kid together. Well I know it sounds mean but I honestly don't feel happy towards her what so ever. I don't care that she's pregnant. We used to live together when they found out I was pregnant. Recently had my son in July. And when they found out, she wanted me out the house. She told me that she knew I was gonna be a bad mother and I wouldn't survive. I had a job, I paid for my own things, I helped with everything. And yet she had the decency to say all that to me. She called me stupid and said my baby wouldn't live a happy life with the  way I was being. But yet here she is with the guy she CHEATED on my brother with. Hearing that she was pregnant just sparked up so many feelings. I honestly thought I was over it but like how the fuck can I just get over it when she insulted me so bad. Everything she said hurt. Ugh... rant over.
