Really need help

i m in love with this guy but he still in love with his ex-gf. she was not in his contact since last 3 years, by that i mean that she avoided contacting him. but she recently added him on orkut and now they will start talking again. and most likely they will get back together. this guy had already told me that nothing can happen between me and him but still i had some hope. but now that his ex-gf is back in his life i m sure nothing will happen between us. i want him so badly i dont know what to do. please suggest me something. what should i do now?

Move on!

I think it is a high time for you to move on. Now you can do it easily and it is going to be your decision. Later when he would ask for break up then it would not be easy for you to come out of it. Take a decision and move on.

Check out lots of guys are looking at you...

Best thing in the end.

You would have been hanging around him waiting for him to recognise what he could have by seeing you. If it was never going to happen then something had to happen to release you from this.
As painful as this will be for you it means it will release you for you to find the person who has been waiting for you to notice him.
Her reappearing could turn out to be the best thing for you in the end but you may not fully appreciate this for some time yet.
