M has no desire for Reunion

Yep, you read it right. The dumb ass ex emailed J (M's sister) and told her that we wanted to meet M. She told him that when she reunited with her birth family M told her that he didn't want to meet his. I am devestated. I wasn't ready for this, I needed more time to come to that point. Thanks to the ex though I didn't get that, with is head-strong attitude he had to go forward with trying to get things his way instead of allowing M to take the lead and now everyone will suffer for it. I am so lost, I know things may change as he gets older, but today it hurts. Today I feel like all hope is gone. I feel rejected and I can't even write, so you know where I am if you need me.
