why am I unhappy?

Basically I havent had a serious relationship for ages and I hook up with this girl who lives about an hour away (I drive though) and we have been chatting for a while, I have already met her dad but I havent met her yet. Im not nervous about meeting her or anything because she really likes me. She is really beautiful and when I show my mates her they are like ‘Wow she is fit’ and all this. So it would be my first relationship in a while and I’m going up there this weekend to stay.

Last night I helped her along while she fingered herself on the phone and it was great, she said she really enjoyed it and we normally talk on the phone at night. However, today I have been really moody and doubtful about how she feels and I don’t have a clue why. I was texting her and she was texting back and I asked her if everything was alright and she said it was. I text her about an hour ago asking if I can ring her and she hasn’t replied but she normally takes ages to reply but I spoke to her just before that.

I know I’m excited about meeting her but am I getting paranoid? Like she has had sex once before she said a couple of years ago and even her telling me that got me annoyed inside and I have no clue why.. can anyone help? I Dont wanna screw things up.

thanks
