Hey OP, hope I'm not too late. Just sending hugs and empathy. It's confusing as f**k out there. If you're not resourced emotionally these dates can sap your strength and you can soon lose sight of yourself - start sort of seeing yourself through the guys' eyes. You sound normal and sweet and like you're simply trying to feel your way through this new modern dating phenomenon. In my opinion your original instinct was correct - don't text first. If a man is interested he will make efforts to chase you up. He will text that night to see if you got home okay if he really cares, or in the next day or two. If he doesn't you're not his type and move on. You can text a guy and possible get to see him again, even get to the point where you're sleeping with him, but people need the space to figure out if they do fancy each other. You can be the most stunning looking woman ever, but without space for attraction to develop and grow, it's to evolve into a long term, deep connection.
As for your next date, do it sooner rather than later after online connection, (don't waste time with endless texting). Ground yourself first, think about who you are and what a lovely person you are, what great qualities you possess, don't try to second guess what he'll think of you. Keep the date short, not longer than an hour/90 mins, make sure you say you have to be somewhere else, even if you don't, enjoy it but don't drink too much, don't give too much away, hold back, (harder than it sounds). Men love to talk about themselves - especially if they're a bit nervous, so this helps. Like you say, end things on a high, they'll realise on their way home they don't know enough about you. And even if you don't really fancy them, use the occasion to practice. HTH xx
