I sort of agree, except I have been involved with some really wonderful, interesting, attractive blokes. I guess, due to not needing to think "Will he support me and father my children?" I wasn't much bothered about finding Mr. Right -- it was much more a case of Mr. Right Now. Being able to break things off when they stopped being fun means avoiding acrimony and recriminations.
I can't think of anything worse than being stuck in a relationship with someone you're not feeling any more, simply because you have kids and it's too tangled up to leave. I'm also eternally grateful that knowing early on that I didn't want kids, took that whole "father of my children" thing right out of the equation.
I'm not in any meaningful sort of contact with any of my exes, and I'm totally fine with that.
