Ok so to start things of this guy gives me signals that I think say he might be interested but then at the same time he dose things to take away all my hopes... I really think he is different because I'm actually talking to him and I feel OK and I don't think he knows that I'm gay... But can a straight guy really fall for a guy like me I'm really slef conscious and I fall hard if the person is really worth it

No, if he is not gay he can not "fall for you" he can like you as a guy and as a friend. Often confusing. You have to ask or talk to him about it.
