We've been messaging back and forth today about going out and being tired from the work week and staying in and what we did this past weekend and she writes this,

"I stayed in. I had a friend over, he spent the night. I'm temporarily staying in a place that i really love, and I have a lot of thinking/readin/writing/resting to do... and it's been a while since I lived on my own.. so that's what I enjoy currently - hanging out at home, and occasionally having a friend over, one at a time. Sounds thrilling, right? I'm unbelievably happy - it's exactly what I need. "

How do I close this?

Well assuming that a few messages have been exchanged I would number close man... looks like she is talking about her personal life and you have built some attraction already.
just say...
"Do you text? I kinda have a texting addiction... Its quite sad actually, I looked up every insurance plan, and the only cures known are cut off fingertips, or cut off cell service, but both are too severe a cure "

this is going to show your interest so remember to make your first text kinda a neg or at least cocky. Something like...
"so is **username** your real name or your Bar name?
~ John"
she will 90% of the time reply with
"no lol my Bar name is *barname* but my real name is *realname* ...blahblahblahblahblah... is John your real name or your bar name?"

then just shoot back "No John is my bar name... I would never give my real name out to a stranger I met online lol!"

Hope this helps and let me know your results
Piece and peace dude!
