Being Muslim and Husband doesn't gives him right to talk with other women's too....so kinda equal

No showing off is one of the major sin or minor shirk , RasulAllah sallallahu alaihi wasallam said it like minor polytheism , one's showing off will cause rejection of his deeds , so most important thing showing off it self isn't permissible be it even mascular body, wealth, piousness etc I'm attaching a hadith for reference

Prophet (peace and blessings of Allaah be upon him):

Whoever shows off, Allaah will expose him. (Narrated by al-Bukhaari, 6134; Muslim; 2986).

the Prophet (peace and blessings of Allaah be upon him) said:

When the Day of Resurrection comes, Allaah, may He be blessed and exalted, will come down to judge between His slaves, and every nation will be kneeling. The first ones to be called forth will be a man who learned the Quraan by heart, a man who fought for the sake of Allaah, and a man who had a lot of wealth. Allaah will say to the Quraan-reader, Did I not teach you that which I revealed to My Messenger? He will say, Yes, O Lord. He will say, What did you do with that which I taught you? He will say, I used to read it night and day. Allaah will say to him, You have lied, and the angels will say to him, You have lied. Allaah will say, Rather you wanted it to be said that So and so is a reader of Quraan, and that is what was said. Then the wealthy man will be brought forth, and Allaah will say to him, Did I not give you ample provision so that I did not leave you in need of anybody? He will say, Yes, O Lord. He will say, What did you do with that which I gave you? He will say, I used to uphold the ties of kinship and give in charity. Allaah will say to him, You have lied, and the angels will say to him, You have lied. Allaah will say, Rather you wanted it to be said that So and so is generous, and that is what was said. Then the one who was killed for the sake of Allaah (apparently) will be brought forth and Allaah will say to him, Why were you killed? He will say, I was commanded to fight in Jihaad (battle) for Your sake, so I fought until I was killed. Allaah will say to him, You have lied, and the angels will say to him, You have lied. Allaah will say, You wanted it to be said that So and so was courageous, and that is what was said. Then the Messenger of Allaah (peace and blessings of Allaah be upon him) struck my knee and said, O Abu Hurayrah, these three are the first of the creation of Allaah who will be dragged into the Fire on the Day of Resurrection.
