Is it normal to imagine a girl is my girlfriend, when she isn't?
Not any girls, but those whom I have begun flirtily texting, or going on dates with.
For instance, I have begun texting a girl whom I knew from High School and had a crush on then. We have a date planned soon, but I find myself spending lots of time looking at her facebook pictures. I will leave facebook tabs from her photo albums open for the entirety of my internet browsing sessions, clicking on it frequently to look at her pictures, over and over again and pretending/imagining she is already my girlfriend. This makes me happy to do, analyzing in detail each picture, how pretty she looks, and how nice it would be to date her.
What's worse, if I am particularly into them (as I am with this girl), I will have audible back and forths with myself of sorts, usually in the car, pretending I am talking with her in a boyfriend/girlfriend type conversation. I say back and forths because they aren't really long enough to be conversations. Sort of just audibly speaking small sentences, that almost are testing to see how it would sound if we were together. For example I may say "Hey [girls name], what are you doing baby?" as if we were on the phone. Almost just to hear how it would sound, to imagine what our conversations would be like.
All this and we have yet to go on a single date, even though we have texted a good bit.
So, is this completely stalkerish/creepy to mentally place a woman in a position as serious as a girlfriend when you haven't even gone on a date yet? Or is it normal to some extent to begin imagining/pretending a person of interest is already your girlfriend/boyfriend even if they aren't, or even close to it?
