Dear prakashraj:

Regarding getting rid of the distressing feeling you experience when you see the girl with other boys, unfortunately there is no way to do that. A feeling is automatic. You see her and automatically you feel what you feel. What you can do maybe, if possible, is see her less. When you do see her, take deep breath and comfort yourself (self talk; talk to yourself like you are a distressed child, be kind, gentle and patient with the child).

If she approaches you in the future- and you feel distress and confusion about her approach- tell her that you will get back to her a day or two after. In other words, you buy time. During that time you relax, think clearly and prepare your response. You are welcome to post here for input during that time, if it comes.
