mmm.. well I think that you don't want to be his gf because you are afraid of losing him and once you start a relationship you know that it's a possibility. But if this is not the reason why you don't want to be his gf then I don't know :/ but just follow your heart and not your head
You can like someone and not have them be your boyfriend. No, thats not stupid at all.
1. No one can tell whether you like him.<br />
2. Your feelings are probably not stupid since the only way feelings can be stupid is if they are not suitable for the situation. <br />
Nothing wrong with being friends. You are just making a big deal about something so minuscule.
Your feelings are being stupid.
