You are now like the WAW, and the tables have turned on him. He doesn't like how it feels any more than you did. He is contacting you even though you asked him to stop constantly calling and texting because he is feeling like so many of us did when it all started. Is he thinking that telling you that he told ow he wants you back should be enough for you to get back with him? Maybe not have zero contact, but a lot less would be good.
I think the signs are good, but like you said, it's way too early to really tell what will happen. I mean, ow hasn't been disposed of, and who knows when that will happen.
Should be interesting at the parties you both attend. vc
