My advice is that no matter how many first dates u go out on, don't assume that the other person wants a second date even if they are the ones who asked u for a second date. I think most guys ask for a second date as way of being polite.
I don't consider asking someone for a 2nd date when you're not interested as being polite. They are giving the other person a sense of false hope. It's also possible that they were interested at the time and later changed their mind. However I do think they could have been upfront, replied to the OP's text and say that "there was no connection" or "I'm taking a break from dating" etc.
What u should have done was instead of texting him and trying to make plans for the second date, u should have just waited for him to message u first. If the guy was truly interested, he would have made an effort. The fact that he blew u off and false indications of wanting to meet again is a 'norm' for all guys on here.
The bold part is not always true. Sometimes a man may like a woman. But not contact her because he felt she wasn't interested in him.
