Okay, now, I’m not saying you need to talk about the way molecules function (unless of course you two are into that kind of thing). But you should AT LEAST be able to hold a bit of an intelligent conversation from time to time. For instance: if he starts talking about something from history (that’s well known), don’t play the dumb card. Let him know you know what he’s talking about. Now, if you really DON’T know what he’s saying, then feel free to say a comment such as “Wow, that’s really interesting. I’d love to hear more about that!” That shows him that even if you’re not aware of some things, you’re eager to learn. And men love that.
Whether you’re texting or not, you never want to appear needy. This is a HUGE turn off for 99% of the male population and is a sure fire way to get him running in the opposite direction. So how can you not appear needy? Don’t respond seconds after he texts you. Give it a few minutes. Don’t say things like, “Oh my gosh I’ve been waiting hours for your text message” or “Thank god you texted me I missed you”. Instead, try saying something flirty and fun like “Well hello there 😉 glad to see a text from you”.
I know a woman who went out with a man she met on OKCupid. The chemistry wasn’t there, so they decided to be friends. He invited her to a party he was hosting, and she brought her friends. Now they’re all friends, and the ladies often ask the gentleman for advice on reading men. That’s a bonus in my book, to have a male friend who can give you a different perspective on dating than your girlfriends!
