21F trying to navigate dating an older guy 31M
So, I need advice seriously, I 21F started talking to this guy 31M, he doesn't live where I live so we met off a dating site, fast forward we had our first call a little while back, sometime last week, we spoke about how he wanted to fly me in just for a few days, for our first date, I was gonna have my own place and everything, he was suggesting protocols and language to make me comfortable enough to not freak me out because flying out conversations can easily get like that. Towards the end of the call, he goes and tells me to think about it and let him know and I agreed.
The next morning we spoke like normal, he told me about his day and I told him about mine, I didn't want to bring up the phone call because I didn't want to sound eager or thristy, following that day, the next day I did not bring it up again as to if I have agreed or not, he was joking with me talking bout how his day is getting busy and that I should enjoy my evening plans (I told him I had evening plans) so the conversation ended. That was last week Wednesday and I haven't heard from him till now? Its dead silent and I am so confused because he is really a chatter box. Communicates effectively, I know I've been ghosted but I am confused as to why?
