Things to scare a bloke off - phoning every day, asking where he'd been, what he'd done, who he'd spoken to, how long he'd ..... get my drift? Too many questions and you're in danger of becoming his mum. The knack is to ask enough to show you're interested but stop short of 'have you changed your underwear' (lol). Not allowing time apart for going out with his own friends. Faking interest in his hobbies is a real no-no! If you REALLY like football, rugby, cricket, stamp collecting, trainspotting or whatever then fine, by all means get excited about it together but if you don't like it then don't fake it or it will be the kiss of death later on.
How long have you known him? DON'T tell him you love him unless you are absolutely certain that he feels the same way.
Things that would make me think she wasn't interested:
turning up too late (more than 10 mins.) makes you feel second rate. If you're going to be late phone. Not returniing calls, by all means leave him hanging for an hour or so, but call, or he'll get the idea you're not bothered. Turning up for a date looking like you've won second prize in a worzle gummage dress comp. He'll think you don't worry about what he thinks - multiply the depth of his agony by ten if you are meeting his mates. Remember, he wants you to meet them so he can show you off ~ yes I know thats neanderthal, but it means you're special to him.
Not sharing ideas or expecting him to always have the ideas for things to do will make him feel like you think it's his fault if you end up in front of the tele on a friday night or that he's not worth the effort of coming up with things for you both to enjoy.
Most of all please ..just relax and enjoy each other's company... if it's meant to be it will be. .
