All marriages will have the odd row George, fortunately we didn't have many during our 49yrs, and when we did they were always over something very silly indeed, and we both knew it was stupid, but pride is a stupid thing sometimes, and often I would come to my senses and say sorry first, and that's was all it took....that one little word "Sorry' but is sometimes hard to say because of stupid pride, sometimes when it was actually she who had started it, but someone has to make that first move, and often as not, It was I who did so, and then she would say...no it was my fault, and she would say sorry too...often saying it a few times...and then the hug and kisses...we rarely went to bed without making up....life's too short.
AIS we didn't have many especially so over the last 20yrs maybe 2 or 3 times, but they lasted minutes, we can all be stubborn at times, no one is perfect but if it's true love then you will always make up quickly.
