Like how we cannot generalise men, you can generalise women either. Depends on what kind of women you are dating- sb who asks for attention or who doesnt. Somebody who is very dependant or very independant; practical and impractical. If you ask my personal opinion: I say you don't have to tell her that you love her time and again and please dont make it a "rule" of wanting to hear "i luv u TOO", in return. Let it be spontaneous. On telling tht you love her time and again, those three words lose its charm and they no longer remain special. There are many other ways to show love. DONT be very possessive. U turn possessive because you dont want to lose her, but u eventually lose her instead. Too much of sugar turns bitter. Relationship is like sand, held them too tight it slips out of your hand, held it lose and it remains. U should also realise the difference between love and obsession....Self-respect for each other, some space, understanding and accepting the person for who he/she is are the key to a very good relationship. Sometimes, some men of our Nepalese society try and impose the attitude of "once-upon-a-time (extremely)-male-dominant-society" attitude and that's when things go wrong. But then, I dont think i can tell about the "specific line" that you are referring to because there is nth specific. You jus realise with time.....i wonder how long have u been dating her..... I hope that helped.....of course ..a little.
