Being possessive is not bad...but make sure you give your beloved enough space so that he doesn't suffocate. Possessiveness in love-relationship should have an extent, as it can become obsessive. Not every possessiveness that doesn't give you breathing space at all or doesn't let 'someone' be free. A little possessiveness sometimes is flattering, a bit more is creepy. A possessive 'someone', who gets slightly jealous is more proud sometimes without knowing that jealousy in any form is disastrous in a love-relationship. 'Someone', who loves you, cannot bear even a slightest thought that yet 'someone' else is also loving the person whom she loves. Similarly she cannot bear if her beloved has any other girl in his mind romantically. But in over possessiveness, there is no space for both, who are in love...!

Kisi bhi relation me possessive hona achchi baat hai, aur apke partner ko bhi samajhna chahiye ki aapko uski kitni fikar hai, aur agar aapka partner possessive hai to aap samjho ki wo aapko kitna chahta hai mean usko apke extra care ki jaroorat hai.
Jab ham kisi relation me hote hain to uske liye apki jo bhi feelings hai wo uska haq aur kisi ka haq usse nahi cheenna chahiye, to khul ke feelings express karo bus itna yaad rakhna ki wo apki feelings ki kadar kare.
