Marriage in Peril

My wife wants a divorce. After affairs, drug and alcohol abuse I don't blame her. Trust has been broken, hope seems lost. We have a four year old, we still laugh and talk together, but are separated. The overwhelming and stomach wrenching constant sorrow destroys me. May God heal her, may she find forgiveness for me and fulfillment in God. May God heal this Marriage bringing it to new heights to reflect his glory. Please pray fervently fellow Christian, I beg you.
