I just made a thread in The Cerebal Approach about abortion and shit. But yo, how did you approach your mom? Like, if she was in a situation where she had to do it, then she would still be feeling guilt about it and maybe that's why she didn't talk to you about it. On the other side of the spectrum, if she did it to get rid of a baby, she still probably feels guilty and if you came at her with an accusation type of approach, she might have not wanted to talk to you about it then. If you haven't already you should sit down with her and just talk about it. People can learn so much from their parents and what they've experienced.
