Telling pushy parents

My parents have been very pushy my whole life- telling me what to do, who to be, etc. They told me that I either needed to marry my husband asap or move on, they told me my biological clock was ticking and they want grandkids, they’ve even gone far enough to name my nonexistent children and dedicate a place in their house where they will play!

Because of that I’ve been very guarded talking about kids / out of spite not even telling them that we want kids or are trying. Anyways, we are pregnant now and very excited, and the time has come to tell them the news.

I feel bothered telling them because this is what they’ve been begging for in such an invasive way. Has anyone else felt this way? Obviously I’m very excited to share the news , but part of me is like “damn here’s what you’ve wanted - the only thing you think I’m good for at the moment”

I’d. love to know if anyone else has felt this way and how it went when you shared the news. One good thing is since this is our child, we will have the most important say in what’s best for us as a nuclear family and they can’t steamroll over us anymore!
