Could This Message Have Put Him Off??

Ok, to summarise. Met tis guy at my friends birthday party two weeks ago (he's her cousin). We've been chatting over Facebook for the past couple of weeks and he sent me quite a nice message on Val's day. Was pretty sure he was interested. He and my friend live together, and last sunday, I visited her at home and spent the day with her. She told me that she'd mentioned to him that I was going over earlier in the week, but as she lives in a separate part of the house as him (it's like an annex) didnt really need to. Out of the blue, on Sunday evening, he sent her a message explaining that he wouldnt be home til the next day as he'd lost his wallet and had had a ''nightmare weekend'', but also said to say ''hello'' to me, and that he'd ''maybe catch her if she's staying'' (in town, for longer than just one night at hers)

So. he sent me a message on Wednesday explaining that he'd been away visitin friends, but that I should ''let him know if I was around''. So I did. I mentioned that I had a few plans but that it'd ''be nice to perhaps meet for a drink or somethin when we're both free". He replied the next day saying that he was planning to go skiiin next week but tat he ''should be around Friday'' and ended the message tellin me to ''let me know what your plans are''.

I replied with this yesterday afternoon...

"Sounds good. That could work actually, may be going to a house party in X Fri night but that's gonna be much later cos everyone's doing their own thing before heading over. So I could be tempted by a bit of X Rd action early in the evening? x
probs easier if you use my mobile 0000000, i'm relying on a friend's laptop and she'll be taking it to work tonight and tomo day''

NO reply. Do you think he felt pressured into asking me out as i'm his cousins friend? Its not like ive been too pushy, as he's done the running so far. Could it be that my message seemed a bit bitchy?? Surely he didnt just 'forget' that he'd suggested Friday night (tonight)?? Dear oh dear....
