No matter who the person is, I always have a hard time saying the words 'I love you' out loud. Even if it's just my friends who find something funny about me and then say 'I love you'. For some reason I have a really hard time saying it back. A lot of times they'll even ask me and say, "Do you love me too?" And of course I say yes, but I don't know why I can't say 'I love you'.

1. You don't want to lie.
2. You don't want to be misunderstood.
3. You think it may change the current relationship, even if you know it won't.
4. You have too much class to use such a lame cliché.
5. You reserve those words for only one person.
6. The only one you truly love is yourself.
Also, this is part of the reason I lost a girl I was with for three years. I did not often share my feelings with her or say those precious three words enough. Now I learned from my mistakes but have not found a girl i loved since. A hard lesson to learn.
Love will probably come again, and when you least expect it. Try not to harp on old mistakes. We all make them, and you learned your lesson, so you can prevent it from happening again. Maybe you needed those mistakes for that reason.
