so this is my first post on the subject, i hope i am posting on the right forum i think this is the best one...

so... problems:
i'am shy
i go into blank's
no attraction
not demonstrating self worth

i would be happy for some pointers on two situations i had:

1. i am talking to this girl i met at a meeting site who gave me her number (i hate the phone). so she was very... whats the word?! enthusiastic, energetic, i like that... told me something about her teacher SMSing here or something, i laughed every time she laughed (felt like wanted to please her), she was very nice so i was scared to neg her (and didn't realy think about it). i was scared every time she stoped speaking as i had nothing to say. i donno... i feel everything is so boring, its like a fucking tast i am trying to enjoy it but can't get it to flow.
anyway... we kept on talking and when she stoped i signed (yeah, not good) but said to myself "fuckit" and asked her out.. she said its not comftarbale that day and scheduled for the next day and i said "fine".
next day she'd SMSing me that she is sick and will call me for when to meet...
i said to myself: "two options: 1. she is bailing me 2. she is actualy sick" so i replied: "sorry to hear, feel well"
i felt like it was good for both cases.
i felf like this SMS was a good chance to exhibit self-worth
i didn't call her and she didn't call me so i guess she is not interested, but the thing is i know she can be attracted to me, she just doesn't know it yet..
i would be happy for some pointers especialy from the point of her SMS

2. talked a girl on the e-mail, after several e-mails we set for a date, i dressed up nice, some porfume, while i was driving i felt as i would come too early so i stoped at the side, she SMS me she would me couple of minutes late (what i surprize...) and i SMS her: "me also" i waited a little longer and then she SMS: "now you are late" i didn't reply and drive to the place... i showed up like 7 min after her.
she had an exitment in her eyes, i think she liked how i looked and i was confidant...
we sat at the table, i wannted to seat next to her but ended up infront of her, we talked (mainly she)... blah blah i felt in-secure i asked he to walk around. i think that was a good move but i think the bad move i let her steer to where she wanted andafter about 3-4 hours of dating she was the one who suggested to go
next day i SMS her "that was nice, maby we would do it next time" (no '?') she said "happy to " same day i pick-up the phone (hate the phone) blah blah, she said she was preparing something so i asked if she would like to call lated she said yes and returned after 2 hours. i had nothing to say and said "what i wanted to say?!" she replied "i don't know what you wanted to say" and suggested she would go to bed i said "good night" and didn't call her since (she didn't also).. its been 2 weeks i think

i feel like i have lots to improve

PS: the 2'nd story pick-up was from a dating site also... i worte her "from the pictures you look a liitle nerdy"
