Search Results: open talk about sex

So I matched with this guy two weeks ago. He’s 4 years older than me. He’s very intelligent, didn’t talk about sex, and seemed to wanna get to know my likes and interests and play 21 questions. I got his phone number and we texted and he texts back right away. We also video chatted a few times. I’m pretty shy and not that open. I’ve been having trouble with friends and needed someone to vent to and vented to him (mistake one I think that scared him away). I also vented about how I didn’t like my family that much (mistake 2 my parents yell a lot and are overbearing). We wanted to hang out on Saturday but I kept giving him the go around because I wasn’t sure if I wanted too. Friday night he said he got a text from his sister and will have to cut the convo short (it was a video call) and there was a family emergency that he won’t be around all weekend for and he’s upset about. I asked if he wanted to reschedule on Saturday - still no answer. He also unmatched with me on the app - not sure if it was recent or not but still. I don’t have the best self esteem and it shows. He isn’t mean or anything and was being polite but I was very vague in my question responses and there was a lot of awkward silences that entire hour we video chatted. We also stayed up until 3 the night before (Thursday night) video chatting and it was still awkward but not as awkward on Friday. I was tired and kinda bitchy and snappy about my friend. The guy hasn’t responded to any of my texts. I don’t know what I did wrong but okay. He said I seem like I wanna open up but I’m scared I might scare him away or something and he doesn’t bite lol and told me to have a good night and try to have a good weekend and he will talk to me tomorrow (Friday going into Saturday) and he never did. He genuinely seemed curious about my likes, dislikes, interests, music tastes etc and thank god not once did he mention sex or anything sexual and I’m so happy about that but still I don't know where I went wrong.
