So for the past 3 months or so I've been single and dating for the first time in almost 6 years. I've gone out with a bunch of girls and had some fun.. but recently met a girl that I really hit it off with. We had a ton of fun and have since hung out quite a few times. I took her to dinner one night and when I took out my wallet to pay she asked to see my I.D., I asked to see hers as well and she refused... she started practicing spelling my last name (long, italian, not pronounced phonetically). I asked what hers was and she wouldn't tell me.. whatever, I didn't think much of it at the time. This past weekend she ended up spending the night sunday night. I left for work in the morning and let her sleep in and said she could leave whenever she wakes up. At work I realize I really have no idea who she is still at this point, and she's alone in my apartment, so I start freaking that she's gonna loot my shit and disappear. I get home at the end of the day and everything is normal except she cleaned my bedroom AND bathroom, that shit was spotless The next time we hang out I ask her for her last name again, she won't give it, I ask why, she says she doesn't have a reason.. I don't push the issue. I'm just curious as to why she'd keep from telling me - does this seem abnormal to anyone? I don't have a ton of experience dating until recently really so I don't really have a good idea of what normal really is I guess.
