Okay #1 no-no don't every say the 3 special words only after 3 weeks. I know it's hard not to at times, but just like males, some female are afraid of comitment. Some times both genders fear that by saying the 3 words means tied down, comitment, no more fun time with the guys, no more mall shopping for the girls. It sucks I know. Sometimes you feel so warm and fuzzy inside and you fear if you don't say it then you'll either explode or you may never get a chance to say it. Try dancing around it by saying things like, I like you a lot, I am developing strong feelings for you, or simple, It's been nice hanging out with you, I would like to spend more time with you. Try those first before you jump to saying'I Love You'
