<human>: Im a 21 year old guy and rarely do i cry. When family passes, i dont show any emotion. Today the girl i loved for the past 3 years, who only sees me as her best friend, told me she was getting married. She cried and i could help myself but to follow. She says she doesnt want to lose contact with me. What do i do? i dont know what to do honestly. Im ashamed i showed weakness. I tried so hard not to give a shit about her and i succeeded. I would talk to other girls and really stopped caring about her as much as i use to, but today it was so sudden. It caught me off guard and i didnt know what to do but express how i felt. Anyways what should i do? i feel like i should just forget about her, but at the same time that just seems like such an dickish thing to do

Can you condense the text into a few key points?
