other than jaanu, kuchi koo, babycheeks there can be some more names too. I have never used these names anyway. I have my own some other decent ways of calling or showing my right on him

No this model is Made in Pakistan
does it mean i will make a perfect wife??? 
Men seek for love, and their stomachs are really big. I am sure he will digest it. Moreover i m not saying that she should give him only the love which is 24/7 coated with honey n sugar n chocolate fudge all the time. thats not even possible n even if it was possible, it will make it boring. So to as an add on taste, you need to get sour sometime. We are humans and ups n downs, mood swings , all are part of life. What i believe is that you should be more patient with the one u love. And believe me some relations worth your patience. personally I wont shout back when he is in bad temper. Rather will wait for him until he cools down. Once he cools down then saara hisaab kitaab ho ga… 
( be it in a relationship where I love a boy or in husband wife relationship)
What I mentioned in my post are not as such lovey dovey things, but i feel they come naturally in u if you REALLY care about someone. You dont have to work on urself specifically. It just happens, he will change you all and u wont even know that.
