Am I a crazy person

I have been seeing my partner for about three months. I'm 28 and she's 23 When we are together the connection/chemistry is great! But apart I struggle with my relationship anxiety. She's not a great texter or communicator so I worry when she doesn't message me back. I don't need a text right away but she goes hours and hours leaving me on read. We also live an hour and a half away so random hangouts are hard. I see her 2 maybe 3 times a week. We have discussed this and she has improved a tiny bit but not much. She has just told me it's just how she is. I do not want to seem needy/co- dependent but I feel she's taking advantage. In the past and recently She has forgotten to call/text back alot. Or she does things like sleep through a camping meet up. I care about this person deeply but it seems like I'm talking to a brick wall sometimes. She is raft guiding over summer about two hours away from me so our commumication will be limited. Maybe an hour a day sometimes. Sometimes none at all. I'm worried in a party enviroment with temptation around and am excuse not to communicate something will happen. She denied making our relationship offical before the summer saying we need more time to get to know eachother. I have been cheated on before and I work she's creating built in and easy excuses not to communicate at times. We have discussed this as well and she was re assuring. But the lack of effort on the commmunication now makes me doubt her effort/intent. I'm worried I may be getting gas lit into lowering my expectations and letting her run the relationship at her convience. She has a part time job and is outdoors alot but I feel like the "I have a busy life and am going though alot of changes" reasons aren't very solid. We agreed to.keep seeing eachother and see how things progress but as always she ensured the ball is in her court so to speak. She really controls when we talk/hangout/ect. She claims she doesn't do this but I disagree Am I crazy?
