Every man reaches a breaking point when they are working hard and not seeing his fruit of his labor. If you are going to break up with him for being a human, be my guest. I believe in a serious relationship there are ups and downs. You can’t live the instagram world in reality. The thing is, if you dump him, he will probably work on his character and become the best version of himself. From what I read, he is already a real man in my opinion by working hard and taking care of his family. Treating you good consistent. He just needs to work on patience, emotions and self control. I think you are overreacting and forgetting it could be worse like you described your ex.
