How do I stop seeking validation from guys?

I think and have been told I am attractive. I do get those "looks" frequently etc. But my problem is that I am so insecure now that I seek validation in the form of getting checked out/stares from guys. If an attractive guy doesn't look at me or just glances/walks past me all indifferent I start to feel not good enough and not pretty. What is wrong with me and how do I change this? :( :(
