Here's something I did when I was in the same situation as you, I scoured the internet (and amazon.com) for trails and rides I had never ridden before. I've even traveled to other states, (KOAs everywhere!) and have ridden in places I've never been. You can leave early Sat or Friday night and get home Sunday. Let the house collect dust, this is for YOU! It worked wonders for me! I recommend you stay away from club rides and other places where your ex is. At least for awhile. No contact, that's the only way to let time do it's work!
