Remember that time you contacted a bunch plummers or accountants or event doctors? Did you really think of those few, who got back to you within an hour or two and were ready to help, as too needy and desperate? I doubt it. You must have thought of them as serious, motivated businesses who show early signs of being reliable and who probably run a tight ship.
Well, it’s not different in dating. Whether you met someone at a bar, a train, or online – if you respond promptly to their text messages and phone calls, it does not make you come across as low status. It makes you come across as someone who makes dating a priority and who is, again, motivated to at least try to make a connection. Promptness alone does not make anyone come across as desperate; it’s the language of desperation or repeated attempts to contact someone, when it’s clear that they are not interest, which will make you come across as desperate.
Don’t be afraid to respond to someone’s text message within a few minutes. If you otherwise like each other, it’s not going to hurt your interaction. Sending lame, boring, pointless or rude messages or sending too many message of any kind is what is much more likely to derail things.
