Thats awesome!
Yes I too am more emotional the older I get. My heart would be broken too if any of my grandkids parent's were divorcing. Seems as though divorce has become common anymore, and it is the kids that suffer. Keeping your marriage is about forgiving your spouse. If God forgives us for the things we do we should forgive our spouse for things they do that we are hurt by.
I married when I was 19 due to an unexpected child on the way. My wife was 18 at the time. When our son was around 2 years old my wife left me. We both got lawyers, and were prepared to divorce. After a number of months my wife realized her mistake, and wanted to come back. I was so hurt by her leaving me I was dead set against taking her back. Then one day my father sat me down and talked to me, basically telling me it would be best if I took her back. I'm sure my father was realizing the consequences for our son if we divorced. So I ended up excepting her back, we built our own home, had another son. Each of our sons have a good marriage and each have a son and daughter, and are both successful. I often think if it wasn't for the intersession of my father, and God to persuade me to accept my wife back. At the minimum I wouldn't have the second son and two grand children I have, and who knows what a divorce would have done to my oldest son's life. We have been married now for almost 48 years, with me being a caregiver for her for the last 17 years. Due to a brain injury when she was 48. Which has been a tremendous burden, but I'm still thankful I didn't divorce her because the result is two wonderful sons, and 4 beautiful grandchildren.
Its not a rant NW. Its the absolute truth. Stay with the marriage especially if there are children involved. First and foremost, forgive, and do what you have to to keep it together. To many couples just think about themselves when getting a divorce, which is what I was doing at one time.
