Moving on?

It's a difficult decision to stop infertility treatment and move on. We've tried to make that decision before and changed our minds back and forth again and again. Recently we've started that conversation once more. Are we just not meant to have biological kids? Should we adopt instead? Should we decide to stay childless? What will make us happiest in the long run? Difficult questions with no definitive answers. We've been married for almost 12 years now...together for over 16 years. We have a great marriage and are best friends. Do we need kids to complete our life together? Are we really any less of a family? We like our life...our fun trips...the cool toys...freedom. Maybe those things are the trade-off we get. And maybe that's not so bad. Maybe it's time to move on...
