So messed up what do i do please help me understand whats happened?

Something amazing and horrible happened. I always thought I was straight but randomly on sunday night I met the one guy I've ever had a crush on.He's a soap celeb. I got chating to him and he ended up coming on to me. We had all night long. The thing is I never thought of myself as being gay and the whole experience was amazing but now he is ignoring my calls and doesn't care. i feel so used and alone. I never wanted this to happen but he is so beautiful and I would actually be gay for him. I wish he didn't do this to me as I feel left in the cold and used. I have no intererst in pulling another guy or inverstigating a gay side. I just feel like I have fallen for him. I don't care about his celeb status or what my friends think. Just how can he be so lovely then not carte in the slightest. Having gay was a big deal for me and to him it's just been a shag. i feel used and fuct up and don't know what to do and can't talk about it to anyone
