Confused…

I love her but its not worth it. But I’m afraid to leave because I feel like I might make a mistake. And that’s my ultimate fear. What if I do leave her and she was the one I was supposed to be with. I see new and exciting opportunities every day. I’m not gonna cheat. That’s not me. But I just can’t stay with her. Its making me miserable. I think. She could be the best thing that ever happened to me. She could be the one. Do I stay and wonder or leave her and feel like I’m making a mistake?
