Am i doing the right thing????

I think you are doing precisely the right thing. It's great that you have realized that he's a big flirt and you might not be able to trust him if you were to fall for him. I would be disappointed too, if I thought the guy I was interested in was genuine and straightforward, and then I found out how he treats the women in his life...I think you are right to avoid him, 1. to avoid the messiness of a broken heart 2. Don't fall for his ertions that you are the only friend he has and loves sharing his thoughts with you, etc (which it sounds as if you are already doing) If he keeps it up, just be ertive and say you are not interested in him, either as a friend or anything else. He is not to be trusted. You deserve better, anyway!
