How should I handle this? I feel like ill regret either decision I make :(?

I believe you should never be too scared too talk too someone. And it sounds like you are with this girl.. Shyness, usually doesn't get you anywhere in a friendship or relationship. Honestly your question made some sense. But im only 16 and didn't really understand the bottom! But if you want my advise, sometimes you gotta bug someone too show them your interested. Cus if you keep a distance real feelings may never come out. So talk too her more, call and text her more. I recommend before calling too text and ask if she's busy. Never just automatically call someone, especially if there busy. That usually sends a bad vibe through eachother. But it sounds like with the more i read your question. She's losing interest.. So i think you should talk to her more, make her smile and etc.. Cus it's never too much if you can make her smile. :)
