At the risk of repeating myself, I'm still not missing the online dating. All the effort you put into sending loads of mails, getting little or no response, sometimes struggling to come up with something to write in a mail as the person's profile is so devoid of information and personality you are almost trying to create a personality for them, for you to interact with.
Then the whole texting, calling and nervousness before the date and the uncertainty.
I'm not missing it for the time being anyway, I must be about 2 months off the sites at this stage, or at least since I last mailed anyone. I moved my OKCupid profile from disabled to deleted a week or two ago.
If you're struggling to find anything to say to someone in a mail because they seem to have no personality, then how are you going to have anything to say in real life?! They're obviously not suited to you, so forget mailing them and move on.
I like the nervousness before the date. It's fun, it's a good "butterflies" sort of nervous. And what's the worst that could ever happen, even if it's the worst date ever and you've nothing to say, you could always make your excuses and leave after a couple of hours. It's not a life or death situation (unless your date turns out to be an axe murderer, then your nervousness may be justified. )
If you hate the whole thing and were getting nothing good out of it, then it's totally understandable that you've given up on it - it obviously just doesn't suit you. Doesn't mean that it can't work out for other people though. You just have to see it as what it is - a bit of fun, and a good way to meet new people.
