YOYO- I think you are giving the guys the message that you are available and willing/able to talk/flirt with them. I am not sure if you mean to be doing that and you only feel bad after when it goes too far, or if you are really not meaning that! I will tell you that I also used to always flirt with guys(I think its part of my personality makeup!) but I finally grew up and realized that there is no reason for me to! Do I want the guys to come close to me and get me in real trouble? I don’t need these guys to ruin my whole life! I am a young girl and there is no reason for me to ruin my whole future because of some little fun now!
I once heard that when you look at a guy straight in the eye part of his neshama goes into yours. I heard it from Rabbi Wallerstein- not sure what his source is. I thought that was very interesting. Why would you want his soul in you?!??!?!? That is why the Mexicans just sit on the corner and stare! They are getting something from you without you knowing it or wanting it!
Stay strong its hard but you can! think about something else!
