So this is a longish story, so please bare with it guys.

I went to Finland last week for a lads holiday and to meet a friend my cousin went to uni with.

Anyway, we were sat in a bar/club and a girl approached me and 1 other friend and told us "my two friends over there really like you two, can we join for a drink" so to our delight we were like "yeah sure". So about 20mins goes past and the girls join us. Long story short, abit of game with the friend and the target who is a HB8/9, we begin to talk.

I secure her facebook page as I was asking if she ever thought about coming to England for a visit and her reply "yeah I'd really like to come visit Manchester with you (as that's where I'm currently based) as I have a sister living in England currently aswell", so abit later on I secure her phone number and text it.

Now its closing time so I leave first while the girls collect their coats etc, so I wait outside to say goodbye. I give the girl a hug, and her friend says "she wants a kiss" so we kiss. I forget how but someone mentions after party at our hotel, and I say to the girl do you and your friend want to come, and her reply is yes. Walking home we are holding hands and talking. We get to the hotel room we start to kiss and get intimate, she holds back when I try to go downstairs so I say thats fine and continue to just kiss. Her friend enters and they go downstairs to smoke, anyway she comes back upstairs and suddenly is game for sex. So we have sex.

Afterwards we were cuddling and holding hands etc and being really close (which is strange for me as most girls I don't normally get involved with after having sex) but this was very different. We are staring at each other for ages and I could tell something was up, so I was whats wrong, she replies with "nothing" to which I reply with, "there is, is it because we've had sex you think I will think less of you now" to which she nodded, so I told her that wasn't the case at all.

I text her the day after I landed home to say it was nice meeting her, also I added her on facebook to which she accepted 2 hours after I text, I said "Hi" and she replied with "Hi!" but then the chat claimed she was typing, so I let her, but it was doing so for 15mins, I refresh and she is offline, so I sent a private message saying

"Not sure what happened before with the facebook chat but nothing was getting through. Sorry if it seemed I was ignoring you!
How are you anyway? How was work with such little sleep? You didn't look too happy in the morning "

She then signed into facebook afew days later, but there was no reply to my message, after about 20minutes of her being online I decided to say "Hi, how are you" so which 5minutes later, she was offline.

Anyway now I've set up the situation, my question to you guys is, I really like this girl, and its very rare for me to get hung up on a girl this easily... I have her phone number and facebook, but how do I initiate that I want to get to know her more without sounding needy or creepy?
I know its only early days, but I am generally shit with girls I genuinely like, so any tips or advice you guys can suggest would be amazing.

Thanks,
Sam
