your a bit young for all that serious shit mate, you need to get out there and enjoy yourself a bit, if you keep being clingy and smothering your bird she'll prob just tell you fuck off. it looks like your being the perfect boyfriend and she's not appreciatting it, so you might need to ask her what she actually wants out your relationship as said most birds love loads of attention, she might not want a serious relationship and thats probably what you dont want to hear so you really need to ask her

when she go's out with her mates then you go out with yours or find something to do. If you keep going on the way you's are then it wont last long
