Hey there!

I have a problem with a boy and it would be nice if you'd read my story and give me an answer :). So there is this boy (we are both sixteen) and I know his since almost three years. Then a good friend of ours introduced us and from the first time I saw him I really liked him. Later the good friend telled me that he likes me also. Then we texted few months and met either through our friend or by accident (we live in the same small town) but I swear there's something between us. My good friend also means he is completely different when I'm with them (and she knows him really well) but then we lost contact and didn't see each other for a few months. When we met after that while we talked a lot and had so much fun (later he even admitted he fell in love with me that day but only to our friend). Then we texted again and we even missed our trainstop one time because we talked so much when we accidently met. He even asked me on a 'date' but I declined because I was so scared. I know he had many girlfriends through the years but however we met again after we lost contact for a few months (again) but we bagan to text again and he admitted to our friend that he likes me ever since he knows me but I also know he had girlfriends while we texted but there have been a few situations this autumn when it was so clear to see that we like each other (the way we talk, the glances...). Did I scare him when I ignored him, broke down contact and declined the date? But I seriously wasn't ready for a relationship and have had many other problems (I didn't even admit my feeling for him til a good friend of mine told me). But now knowing that I do want a serious relationship with him doesn't make it easier. Besides I know he is in a more serious relationship right now then the ones before, but in the end I'm always comes back to me so am I just the one girl which didn't make it easy for him? Or does he really like me especially after what he said to our friend?
Thanks for all answers :)!
