I met him online and I�m so obssessed about him. What can I do!?

I met a guy online and I�ve been talking about him for a few weeks now and we�ve been sharing a lot of things with each other, he has told me a lot about his lfe and I have told him as a lot about my life. i got to a point where I have strong feelings for him and I love him and think constantly of him..We talk every single life for like 4 hrs each day but he havent met yet in person and that makes me feel bad cause If i would have met him it would all be much easier then having a "long distance computer relationship"..sometimes I feel that I am so attached to him and I dont wanna seem weak infront of him by feeling the way I do about him..i dont want him to think bad about him..i wish i was less dependant and addicted to him but he�s so sweet and nice and understands me...i guess i wish i was stronger and more careless abut how i feel..its so hard not having him around..
