I’m crying I know I shouldn’t gotten feeling but I did

I had a one night stand and then the guy unfriended me from Facebook I’m crying he was so nice to me I though I would see him again my heart is broken i really liked him. We did it without a condom he wanted to cumple inside I told him not too he didn’t. I still have his phone number he still has mines on WhatsApp but I think he will remove my number also we had great sex I feel heart broken 😞 he was just really nice I he was drunk also last night I don’t know if that’s why he unfriended me like why did I do something wrong I don’t know I know we both said nothing serious but I thought we would keep seeing each other. He picked me up and took me back home he still has me in WhatsApp it’s weird but I will try to forget him I knew it was just sex but was wanting something else when I met him in person I loved his personality 😞
