Self-counselling is usually not enough, as we are all limited in viewpoint, especially when it comes to something so emotional.
My advice is to do everything you can to work things out, with one caveat: there is no excuse for abuse - emotional or physical.
Also, many people seem to believe that if they "fall out of love," they need to divorce. Actually, the commitmment of marriage is such that couples shoudl stay together during those times, and most often, a new, more mature love emerges. Usually, when we "fall out of love," it actually just means that our preconceptions about romantic love are being challenged by messy reality.
Also remember that mature love is never unconditional.
Wishing you the best.
