Replying to Why cant i talk to her normaly?

Theres a girl who ive liked for a while and we have gone out previously. i have trouble not being awkward and sometimes shake when im around her then blame it on being cold. i am a romartic guy and i have been told im cute and funny but for some reason i just cant get it together when im around her!!! i have a very bad memory and sometimes talk about the same things twice. i get lost in her eyes and forget what shes talking about sometimes. then when shes done talking i just laugh or something like that. we are going out now and i know she likes me a lot. but im afraid il lose her again if i cant start talking to her normaly. i have a creepy smile and am usually quiet around her. her friends think im sweet but my friends think im awkward. what do i do? should i talk to her on the phone more or just set aside my friends to try and make this work? please i need advice!
