Sex drive can be the most powerful factor that effects a man’s behavior . He won’t say it , won’t show it , but its there . Being a daughter there is no way you can understand it . Though any irrational behavior from his side just to make it happen is natural .
Best advise would be to let him have it . He’ll be all over his new wife for sometime , and then it will get normal .
Thats the way we men are , hard to follow just our real brain
