Sock, I think from what we know about you and how you are second guessing yourself a lot, I would STRONGLY advise you remove Casual Dating from your profile.
For cynical me (and men that do OLD, casual means FB/ONS and NOTHING else)
I don't think ONS or FB is a positive environment for you to be in mentally to be honest. If you were more robust, you wouldn't be as self doubting as you appear to be, whatever it was that you did on your date wouldn't even warrant a mention here cos it wouldn't be an issue.
I think the possibility clearly IS there for a relationship, but you need to try to understand why you are putting out the impression that it's not serious, and not necessarily likely to be. I'm concerned that is out of insecurity and fear rather than a conscious decision.
I am of course no expert in this myself, what with the 'I'm not sure why i'm with you, it's easy' rejection after a year, when Mr RockGod was uncomfortable, i immediately thought it was him not fancying me and wahey, up went MY barriers. I gave up. Tis me all over. Out of fear of rejection I bottled it. I did say this to him tonight. He's had his own fair share of rejection so would retreat, hurt, in a similar fashion.
I'm not going to chase him. i have contacted him, I have said I'd see him again, and have made tentative plans for the weekend, even offering to offered to move plans on Monday if Sunday trains are rubbish. Up to him now.
