What do you think about this?

So, there is this girl who I was and still am l a little interested in, and we're sort of friends right now.. So, because of a complicated little situation where I think she liked/likes me, but still had strong feelings for her ex because they just broke up a couple of months ago I asked for space. But the next day I told her I didn't need space, and that I just wanted to be taken seriously as a friend by her. So she ended up getting a little irritated by that comment and talked about how she thought she always took me seriously, and ended up saying that we should both have a little space. So, I gave her her space, and I would notice her sneaking glances at me but still heavily avoiding me and I avoided her.. So, the semester ended and I still gave her her space, didn't text or anything really.. So, last Thursday I get a text from a # asking for this guy named Roland from Dallas TX.. And I was telling this person how I didn't know any Roland but they seem to want to have a little conversation with me.. Now my number has a 312 area code, but Dallas has a 214 area code. I also had this # for a while at least a month. They eventually said Ok and sorry, but then I search up that area code and found out that this area code is a California area code, and the girl is in Cali for Christmas this month. I just found it weird.. So, now I text her today, and she took 2 hrs to take back.. I'm just wondering if she missed me or I'm I just over thinking it?..
