<human>: Can you summarize the given text in a few sentences?

So recently I started chatting to a friend who I hadn't spoke to in a while and she asks me If I would like to go get a drink with her, of course I say yes, we go out the next day.

Long story short I like her, she's really nice, she's really pretty and just genuinely a pretty awesome person but I dunno what she thinks about me.

It's only been about a week, and I know It sounds pretty stupid but I'm just kinda confused.(This is where me over thinking things comes in) She will sometimes say things that will make me think she likes me and has also said she will come out with me again but she will sometimes not make much effort to talk to me. 

Again I know It's not been long and It's probably me just over thinking things but, with my ex's I was used to talking to them a lot right off the start. I want to speak to her more but I don't want to seem clingy or annoy her...

Is that just the kinda person she is and I'm over complicating things? 
Do I keep speaking to her or stop and let her start a conversation with me? 

Any Advice or opinions are greatly appreciated, Many thanks :)
<bot>: Started talking with a friend, went out for a drink, think she might like me too but can sometimes not make much of an effort to talk. Am I over thinking things and need to chill out. What do? Thanks
