Maximum of 10 texts a day! Bloody hell, I think over the course of a couple of weeks I've only exchanged 10 messages in total, most of which revolve around "sorry, I can't make it that day, are you free Friday?" "no, but I can do Wednesday next week" etc.
Perhaps its all the texting that's clouding the issue and making these dates seem more important than they actually are.
Men are fragile little flowers (!) and they are easily spooked apparently. In my very limited experience, the less interested you are in them, the more they want you - its perverse and I hate playing games, but I truly believe you have to try to think like one of them, switch your emotions off, compartmentalise, don't see it as some 'big picture' that is a reflection of your worth as a person. Its just that these blokes weren't right for you. So what? Someone will be.
If you can honestly look at yourself and say you are being true to yourself, acting naturally and being honest, then that's all you can do. Keep putting yourself out there. And no-one will be judging you for your 'inability' to get a second date - for starters you don't actually have to tell anyone who you're seeing or whether you've seen them before. Secondly, if these people care or matter, they won't be in the slightest bit interested in how often some bloke wants to take you out.
