<human>: To start off, I love my girlfriend and everything feels right but isn't right (if that can ever make sense). We're on totally seperate schedules and I feel horrible for feeling the way I do. I'm a supportive boyfriend, say little and listen more kind of thing. Recently, I just feel like she doesn't try at all, but when she does it's at the worst possible moment. I'm her first real boyfriend and she doesn't know any better but here's what's been eating at me. 
My girlfriend works and has a ton more things to do in school and volunteering, while I have too much time on my hands. I fully understand and I do my utmost to never put anything from our relationship on her shoulders, that would be just wrong. She usually drops me off at my house and whenever I try to get a kiss or two, she tells me that "she has too much work to do and that she's very busy." When I text her maybe an hour later, she's not doing the things that are making her "busy" and I constantly see her doing work before her classes and in the morning. Why brush me off so hard everyday, just to not do the things you told me you had to do?
Every weekend I ask her if she wants to hang out and she never asks me. This doesn't bug me so much but whenever I do ask her she gives me a passive aggressive answer about how busy she is with extra details when a yes or no would suffice.
Then when it comes to intimacy, I hate kissing in her house while her parents are around. I could just be old school but it's super disrespectful and I feel like sometimes she just likes the "danger" of it, and that's annoying. Other than that, I have to initiate absolutely everything, it's understandable around 3rd month but it gets old. We don't have sex which isn't a big deal, and I'll live. Yet, she never says anything sexy to me, the closest thing I've gotten is "I miss you". Other than that, nothing.
I'm probably nitpicking but it justs feels one sided.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Boyfriend feels like girlfriend isn't giving an effort and might be nitpicking. Is she putting in an effort? If not what should he do?
