A Created Opportunity Outing?

I met up with the girl that I was fond of last week. Had to meet her because she left her phone with me. It was a short outing, but it felt very gd. I felt very warm inside when she came late and she apologised to me, putting her head and hands on my shoulder. I was startled by her actions but it felt warm and nice inside. We spoke a lot during lunch, whereby we chat a lot and had very close eye contact. I wish we could chat and spend that whole day out, but she had something on. We went window shopping together and it was as if, I was like her bf, except that we didnt hold hands and stuff. I really really like her, but does she feel the same way? Its gonna take a lot of effort and I do hope I can win her heart. I just can't stop thinking of her every min of every day. I'm trying to control myself and hopefully in the end, we can be together. She is the only girl that I've ever dated, that I want to share my happiness and sadness with. Its like, I have a goal to look forward to, to be there for her and look after her. The funny thing is, when we are out as a group, we dont talk much. But we're alone, we can talk till the cows come home. Why is that so? Haiz, its so confusing. I can't wait to meet her again, and this time, I hope it will be more enjoyable and fun!
