<human>: Can you give me the gist of the text in a nutshell?

I've been dating my GF for about 2 months now. Before we were in a relationship it was a great time all around, we had lots of fun and went out together at least twice a week. She's a very busy person with schooling, volunteers, work and friends but we were getting along great. I have been in the dating pool for a few months now and have dated lots of people, none have ever clicked as well as this girl and I did. On our 8th date I asked her if she'd like to be exclusive, she said she did, we both seemed to really like eachother and that made me pretty stoked. Well, since then we've seen each other twice for like a grand total of four hours. She's busy and I knew that going into it, but on top of her being busy, she doesn't seem to want to try and organize anything in general. 

Since we've started dating I've asked her if she wanted to hang out 5 times in 2 weeks, she's said she is busy 4 of those times and has only agreed once. She will apologize for not being able to hang out but won't try to reschedule. It makes me feel fairly rejected and I'm not happy with it at all. I've stopped asking her to hang out in hopes that she'll be the one to initiate it and nothing has happened yet. Earlier today I was particularly wanting to be flirty and try to engage something so I texted her, "You still owe me that kiss" (she does) and she replied "I'm sorry". I haven't even responded to it because it feels like it's just on a loop.

I can't ask her to change her life and I don't want to make her feel bad about it. How do I go about fixing this? Do I talk to her and say that I need her to be more clear about when she can spend time with me? Isn't that demanding? I'm honestly pretty terrible at relationships and I really don't want to act like an asshole.
<bot>: New girlfriend has a full life already, I don't feel like there's room for me and I don't know what is okay to do or say.
