She said she was jealous when I said this !!! why was she...please help me..pleaseeeee. .10 points for the best answer?

Relationships are hard, I can't even imagine being in a long distance. She's jealous because you told her that a girl likes u a lot and asked u out, knowing she can't see you or actually be together is bothering her she prob feels like she doesn't know what ur doing or if u will actually go out with this girl. But I give u credit for being honest w her and I would say that to her..most guys wouldn't even bring this up or tell their gf this and u need to let her know that u want to be honest and not hide anything.

Just because this girl likes you doesn't mean u want her. Tell her that u want her and no one else. Hope it works out!

Well there are a few possible reasons

But keep in mind girls don't like to hear about other girls in your life unless they obviously don't like you.

One she obviously likes you and wants to be the only girl you get close to

Or two she is just being flirty and saying it to get your attention back to her which is obviously working so 1-love her point :p. or three she is just attention seeking

She loves you and does not want your heart to be stolen. That is how I see it with my mind's eyes.
