Idk what to do

I haven't been in a legit relationships in over a year, maybe a year and a half, I haven'y even thought about dating. I am only 18 and that's young, but that doesn't stop my from wanting a serious long lasting, hopefully a life long relationship.(my longest was 2 yrs.) Okay I'll start with the problem now. I met this girl about 4 weeks ago online, and we have only been on 2 dates since. the first one(when we met 3 weeks ago) we really hit it off(went to a pool hall with her friends), our 2nd date last week we had a great time, or at least I did, i'm guessing she did too because we have plans to go shooting next weekend. but our second date we did some archery at night and after we lost/broke all of my arrows we cuddled in the back of my truck looking at stars, it was cold so we went inside my truck and turned the heater on, chatted and cuddled for a bit, outta no where we both just started making out and we did that for a while but didn't really go further. I then proceeded to drive her to her friends where she was staying that weekend and she invited me to stay the night, I did and we just cuddled. we woke up, cuddled, kissed, it was super bowl Sunday so we both went continued on with our days apart from each other. but before I left we were talking about random things and she said the only thing that bothers her about me is me age, i'm at and shes 20, we are 2.3 yrs different. ill tell you about her before I tell you the problem. shes 20, lves over 2 hrs away. but goes to school an hr away. and stays at her friends on weekends an hr away but only has 2 months of school left then shes getting her own place 20min away. here is my problem. I have to start the conversation most of the time, if I dont text her first, we most likely arent gonna be talking that day. we are getting along absolutely perfect when we hang out, we like the same foods, places, activities such as hiking, camping and what not. but from conversations I have had with her, she seems to come from a party past, a few crazy drunk sex stories in there too. 1. I would like to know if there are any faithful party people out there. 2, what is a reasonable amount of time before talking about a relationship. 3. what are my odds of her accepting the age difference and us being together? 4. how soon is too soon to talk about a relationship and things of that sort? but besides the crazy stories, I really like this girl and would like to be with her for ever and really hope she is who i think she is!! I have a hard time sleeping cause I think about her so much. if you need any more details feel free to ask and I will reply, thank you!
