I had the same problem few months ago, but luckily I solved it and I hope you'll do it soon. My problem was that I had perhaps an hour or maximum two to ride per day and I rode the same 2 routes and it get pretty bored. I rode at the same time, the same place, same people and animals were along the way... terrible deja vu 
Than I decided to change something... anything.
1) I started to ride at dawn, it was so refreshing, you couldn't believe it.
2) When it was to early for me to wake up cause I didn't have enough sleep I put my bike in a car and than drove to some furtherer mountain/place/lake and I drove my bike on and off the mountain/... I saved much time getting there with a car so I still had the time to do my chores/homework/gardening etc. The mileage I did per day was the same but it was much exciting
3) I persuade one friend of mine to ride with me (she borrowed my DH bike) and we ride the "old" route at much, much slower speed. But I had someone to talk with.
After a while she fall in love with biking and bought herself a bike and now we ride a lot together, much faster, of course
I hope some of this will help you...
