Broken - there is rule 5, if it's not fun, stop. There is also 1,2,3 and 4.
Don't feel like this date will 'fix' you, if you're really feeling broken. You need to be okay with yourself before you can be happy with other people. You need the thick skin to deal with wankers, disappearers, and rejection. You don't owe the man anything at all, and all the emotional investment may screech to a stop when you actually see him.
But, if you're open to taking the risk, you may have a nice evening with a nice bloke, without any pressure. There may be chemistry, there may not. It could be there is chemistry and you're not ready to deal with it yet - which is fine - it's a lesson learned.
The point is, you can only date if you're ready to, not because you think you should be ready to so let's go and do it. And also, conversely, that getting out there will make you more prepared to get out there again. No one can make the choice for you and we'll all support you whatever you choose.
