My girlfriend and I have been together for a while now. I love this girl and she says she does too. But I found out that she had feelings for her best friend and she said she realized she was in love with him after she found out she was in love with me. Hes a friend also a good guy too but he says he doesn't like her she's just her friend and he told her that too she said. Idk what to do its bugging me a little I just need some advice please...

Move on. This is stupid children's games. She doesn't love you. You don't just "find out" that you love someone. And you don't "find out" that you love two people at the same time. She is confused, and you need to leave her with her thoughts and let her decide for herself. YOU need to move on, and ignore her drama.

Leave and don't wait on her to sort her feelings out. If she is so confuse than let her be confuse by herself don't get yourself caught up in her confusion. Sorry this happen to you but this happens to the best of us and always the good ones.
