Relationship with the opposite sex is a big challenge. Whenever we get into a relationship we somehow change and start treating our half differently.
Men hunt and women nest, that's the law of genders and it works in a relationship also. Men are eager to chase women but once they got what they wanted they become uninterested. Women, vice versa, do their best to save the relationship even if it involves cases with abuse and humiliation. Why is that? Once we break men's plans or don't meet their expectations they turn into wild beasts and it's not a big deal for them to just insult a woman by talking freely and hurt her feelings. I'm no men-hater but I've seen many couples that ended up in abuse and hatred for each other based on nonsense. May be it was women's fault but in anyway that's not the reason to become a low person towards the better half.
