I would highly recommend taking the Dynamic Marriage class that our church offers twice a year (there's one starting in Sept). You can read a little about it here:

My husband and I went through it a couple of years ago and it was well worth our time. During our class we had two separate couples that had already divorced, but were considering reconciling, and both ended up remarrying shortly after the class ended. (And in one of these couples, one partner had no real interest in reconciling, but agreed to come anyway, so it was especially amazing.)
It's a lot of work, but if you do it, it pays off. I recommended the class to another friend of mine; she said it did more good for her marriage than any one of the number of counselors they had seen.
Just wanted to throw that out as another option.
