I can't say I have ever been 'scared off' by someone telling me they love me too early in a relationship.
What has happened is I've realized that she was attempting to either manipulate me into loving her in return or that she was not in control nor understood her own emotions. Which, caused me to end the relationship.

How can anyone love anyone if they have only known them for less than a week? How can anyone love anyone they have only associated with online?

Love needs time to establish and grow. Time is a major factor.
I agree that not everyone is trying to manipulate but many are.
If the three words come too soon it is a warning flag.

Saying I love when you do that or I love when you say things like that is different than saying I...Love...YOU. You can't really love someone until you know them. You can love everyone like a hippy but that love is usually hollow and doesn't stand the test of time.
People lie.
They lie to others but they also lie to themselves.
A lot of people are in love with being in love and it usually has nothing to do with the other person.

everyday
I tell my son I love you
when he goes to bed
and I always end our phone conversations
with I love you

Telling someone I love them is hard since it takes a very special person for it to mean anything significant.

I usually tell my brother and my niece and nephew that I love them when ever I talk to them - my closest friend sometimes - I think it's important to tell the people you love how you feel. You can tell if someone loves you by their actions, but for me I like to hear it said - I never get tired of hearing it,

Sure, I've been burned quite a few times. I think most of the people using online dating sites have been burned at least once.

Love at first sight is just another way of saying infatuation.
Infatuation may or may not actually be love. There are many people that don't know the difference.

Personally, I am a loving man. I love in the moment. I live in the moment.
When love establishes itself in me for another person I experience more moments feeling love for that person than moments I don't.
That track of experience determines the degree of love I feel for them over-all. To proclaim love for them, I need a love-filled history with that person.

Its possible to love someone without having desire.
I have told co-workers that I love them because I love the experiences associated with their presence. Most people that know me, man and woman, will eventually tell me they love me. I treat people with dignity and respect.

Its when I am in an intimate relationship with a woman that I have strong feelings for that I am reserved in accepting their proclamations of love for me without corresponding experiences.

Its when I treat them with dignity and respect, they are not used to it and immediately think they love me, without truly knowing me. This is a reoccurring experience I have gained wisdom from.

You live love in everything you do, therefore it's not necessary to keep saying it...............if I said such a tired worn out Hollywood cliche to my love it would make her think that I'm having an affair

I have very few in my life to say it to, but hold no affection back when I get the chance to show it. I could always use more people to say it to though.

agree...
