Can a man according to Islam show his emotions?
Prophet Yaqoub cried when he lost both his sons. Prophet Muhammad cried when his son Ibrahim died. There is no general prohibition on showing emotions. Harmful shows of emotion, such as breaking things out of anger or sadness, are forbidden, but you don’t need religion to tell you that. Islam teaches us to aim for the greatest good and avoid things that are harmful to ourselves and humanity, using this principle, you can determine which shows of emotion are acceptable, which ones are disliked and which ones are clearly forbidden.
And God knows best.
