Online, you're providing each other with the good aspects of being together as far as communication and support, but you don't have to deal with the realities of paying bills together, or being annoyed when they leave the toilet seat up or don't put the food away in the fridge.
I have very little experience with dating websites. My feeling toward dating websites is what most peoples is: If it works, great. If youre serious and legitimate about it and know what youre looking for, then from what I hear, its definitely effective.
Life experience is what defines our character, even if it means getting your heart broken or being lied to. You know, you need the downs to appreciate the ups. Going on the adventure or taking that risk is important.
