<human>: Can you condense the text into three sentences or less?

We are both in school (at the same school) and  have been seeing each other for around 7 months. I'm quite crazy about this girl, but the relationship we have now feels emotionally and physically lacking for me. When we spend time together, its fantastic, but I only see her around once a week and we only spend a night together like once a month. Too many times I will suggest an things for us to do and she'll seem super excited about it, but when it comes down to actually putting time aside to do it, she'll be too busy, and it won't happen. Now, the nature of her program is busier, she has other jobs/volunteering obligations and she has a much larger set of friends in the area that she keeps up with, though, too. I do my best to give her space when she's super busy, but still be persistent about finding times when she is free. I feel like I am a much more marginal figure in her life compared to how I feel about her. Neither of us are particularly good communicators about relationship stuff, but it's gotten to the point where I need to say something. I am dreading putting an ultimatum on minimum physically/emotionally intimate time, but given that we've been seeing each other for seven months, maybe I just need to stick up for myself.
<bot>: There is a mismatch between the apparent amount of relationship time/effort that the girl I'm crazy about has for me and the amount of time I feel I need. I want to talk to her about it.
