Pushing away a girl.

So I had a first date with a girl on Monday and it went really well, at the end she said she wants me to show her around my hometown sometime so that was great.

trouble is I got too ahead of myself now and already told her I really like her (about 3 times i said this) which was dumb, I think i definitely annoyed her last night. I had also sent a lot of texts and had no response but I am not surprised as I was acting a bit too intense.

I don't think I have completely messed it up yet but I need some advice on getting to normal with her, I have came across so far as clingy and rather desperate I think..

a friend told me that I should lay off and stop jumping on her the moment she signs on msn and that I should stop texting so much which I agreed with, he also said that I should play it a bit cooler by talking to her a little bit (about 10 mins after she signs on) but then say I have to go and that I will maybe talk to her later...etc

Anyone got any advice? I messed up with her pretty bad by getting too into it already but I really like her and wanna get that second date still, I was planning on seeing her next week sometime so I still have some time to fix things and prove that I am not clingy. I just hope that I can sort things for next week so she is willing to come over to my town.

Do you think it's still fixable? I know I just need to 'play it cool' but it is harder than it sounds, now however I am at the point where I know it's the only way forward!

I'm not actually a clingy person when in a relationship though, but after a first date that goes well I get a bit too into it and that can be a big downhill slope to come back from.

Any more advice? I am a bit hopeless with the proceedings after a first date and have only had 1 semi-serious relationship in the past.
