Marriage problems

Please pray for my wife and me. We have been having issues for years and they have reached the point where we are fighting at least once a week. My wife keeps telling me I’m not loving her the way she needs to be loved and I don’t know what to do. Please pray we can work through our problems and find a way to do life together better. Please also pray for my own selfishness and defensiveness, as these almost always come up during our fights.
