Wow, thats hard, but I feel the same way if any girl talks to my boyfriend. I just try to take it as a compliment that they think he's soo great but I know he won't leave me because we have history, If he's upset he comes to me but sometimes I can be a .....yeah and well he takes it and then gets mad later, we apologize and make up. We have a great relationship even though I can be a very jealous girl. Any amount of Jealousy in any relationship is bad. In my life it means your insecure about the relationship, and yeah sometimes I am. I bet you may feel like that sometimes but hide it with anger instead. I use to do that with the previous boyfriend and he ended up leaving me for real and then I found my current boy and he's awesome! If you know your girl won't leave you then just take the other guys hitting on her as a compliment that she chose you instead of them, there the jealous ones, you shouldn't be. Enjoy your girl and be happy she's with you not them.
