my gf and i have been together for about 6-7 months, the relationship is decent, and so on. my dilemma is this; she has been acting weird lately(past week), if i had to explain it i would say that she is trying to act like she doesn't care, saying she'll call when she doesn't(never used to do this), very minimal details about everything, we only hang out once in a while, etc. the list goes on, now as i typed that it sounded like someone that is cheating, but i really don't think she is, however i could be wrong. what could i do to get a better understanding of what she is doing, thinking, etc? also what could i do to throw her a curve, she didn't call one day until later around 9:30 and asked me why i never called all day, i said i was busy, things similar to this?
