Is it just me or is talking to guys so frustrating?

I’ve trying to put myself out there and date. I’ve been in a relationship for 3 years and I’m officially done with it. I went on a couple of dates, and one of them was the best date I’ve ever been one with anyone. I want to continue talking to him but lately he’s been telling me that he wants it to be casual and that he’ll tell me when he’s available to hangout again. I understand that, people have busy schedules I’m just trying to see if he still wants to talk to me or message me because I feel like I’m texting him more and more. And what’s crazy is that he is not that only one that’s acting like this. From 20 guys I’ve been talking to in the last 3 months, I’m not talking to anyone currently. And I think it’s just me, I guess I can’t read social cues. I lay in bed and wonder if I’m supposed to be single for no on ya know. Im sorry I just need to rant because this is emotionally and spiritually too much. I see so many happy couples around me and I’m this community and I wonder what are they doing or saying that I’m not. But again I’m fine right now I’m just waking up each day.
