My son’s birth mother died last night and I’m just mad

I have a step son, I’ve raised him since he was 4 bc his birth mother left him and never came back. She wasn’t a good mother and he saw her once a year on his birthday but last year she didn’t even bother. She’s a terrible person, she tried to get him back when his case worker told her I was to adopt him and she had no right to. She was abusive and I just hope she rots in hell bc it’s what she deserves. <br><br>I’m just mad that I have to sit my son down and tell him she’s dead and he’ll be so sad bc he still loved her and that just makes me mad. I just hope he won’t grieve to hard.<br><br><br>EDIT I’m so sorry to the people who lost family and loved ones and are using this as their way to open up, I didn’t know this would give people an opportunity to open up and I’m sorry people are having a bad day and getting triggered.
