cause i see you all as my only friends
this is why...
dude, how long have you known her for? because you can't just know her for 2 days and say "i love you", but you also have to "KNOW" her on a personal level, because saying those 3 words without knowing anything about her might make you look desperate, in that case, the 3 ideal words you can tell her is "i like you", it tells that you are interested in her and it shows
self confidence(WOMAN LOVE THAT)
but if you actually know her on a personal level and have been seeing her, dont bring up the "i love you" subject, just show her that you do with spontaneous romantic moments of things that she likes, showing that you know what she likes means that you listen and know about her.
