I found your comment about no desire to date interesting as it is also happening to me. And the funny thing is that I actually get a LOT of female attention now that I am in "no desperation" mode. I LOVE being single, in fact I love it so much, I wonder will I ever desire a longterm relationship again. I suspect I will, once I meet the right person.
I focus on my kids, I focus on my photography, I focus on my job and on my sports and travels. And that's plenty for keeping me busy. I also have 0 desire to interact with my EX, I mean I have no problem interacting when it comes to the kids, but other from that 0. And I am fine with it. We coparent amicably and I will be forever grateful for that, esp. when I read on these boards how bat$hit crazy some exes can be.
