Carly,
I am amazed at how few men there are out there that don't want kids but don't give up, they are out there. I am lucky that I found two guys that accepted my choice to be CF. The first even got a vasectomy but after a few years together the relationship was no longer right for me. My current BF and I have been together for 4 1/2 years, and while he would prefer to have kids, he loves me enough to give that possibility up. Now, two years after my Essure procedure, we are still completely happy together.
You are still young, you will find the guy who is right for you.
