I am still standing with my daughters

I wanted to give an update on my sitch and I think some 2x4s are needed at this point.

Actually I think you did fantastic! You're letting him pursue the D, you're not helping but you are not blocking it either. You told him you are not dating but are leaving the door open to it- perfect. You said you're happy to move on without him, just right. Even the joint birthday party was in my opinion a good idea, as long as you can do it without expectations then it is the healthiest thing to do for your D. Plus it's an opportunity to show him what he's missing.

I wished him luck with the pursuit of his happiness and told him I am in my own way happy where I am today. There was no response from him to this.

GOOD! You know why? Because he is taken aback that you are not pathetic, weepy, desperate and begging him to take you back. He's more than a little stunned to discover Plan B is a rug that's been pulled out from under him. WELL DONE.

I still dont want a D but at this point I am more disappointed than sad if that makes sense.

It does and that is a healthy attitude.
