<human>: Can you succinctly summarize the text in 1-3 sentences?

Hey good people.

I met this girl at a bar a few weeks ago and she slept over at my place later that night. Texted her a few days later to meet up, but she said she was out of town. I didn't care enough to pursue it more, until she texted me about three weeks after that to see if I was up to get drinks. I took her up on her offer and we met up. Went back to her place after, didn't sleep over. 

Now, here's my issue. I have a tendency of getting into faux-relationships even when I don't want to, and I think this is one of those situations. 

I just wanted to ask for any advice about ways to keep this casual so as not to lead this girl on - that's my primary concern, really. Arguably I've already done that by hooking up, but short of putting an end to that - is there anything I can do? I tried not to be too affectionate and date-y when we last met up, but I'm not 100% sure it worked. We haven't texted at all since. 

And how often can I reach out to her to hang out? I don't want to treat her badly, but I do want to send a casual message without explicitly telling her unless it comes up (in my experience the un-preempted let's keep it casual convo is always a major buzzkill). 

Thanks much for any advice!
