My abortion makes my parents feel uncomfortable

When I bring up my abortion with either my mom or dad they always try to revert the conversation to something else or change the subject quickly. My mom says I shouldn’t be treating it like it’s something normal which I’m not, I bring it up on occasion when it relates to something. I don’t bring it up around strangers either I literally only talk about it with my mom, sister and dad who act very uncomfortable about it.

I don’t talk to the guy who got me pregnant anymore, I haven’t for about a year now because he is abusive so I don’t have anyone around me who’s been through this. I’m not ashamed of it, it’s just something that happened to me and they expect me to be ashamed of it and never tell anyone about it. My mom told me I should never tell anyone I had an abortion not even my future spouse.

I told my ex about it and he was supportive of me and when I told my mom I told him, she was horrified saying to never do that. It’s not like i willingly bring it up randomly it’s only rarely and with people I trust. I don’t use it as dinner conversation or anything like that. Should I just stop talking about it and am I the insensitive one?

I want to make it clear: I do not tell people about it randomly. The only people who know about it are my mom, my sister, my dad, my ex, the guy who impregnated me, and some of my family. And the only reason some of my family knows is because my mom told them I was pregnant so obviously when there’s no baby you kind of put two and two together.
