I Feel Taken Advantages Of... And Neglected?

So my boyfriend and I have already been going through a tough phase for the past month. We've together for 6 months and everything was perfect until last month. He used to make me feel like the most special girl in the world and treat me like a queen. I lost my virginity to him and everything. But now he's become really distant, like he spends more time with his friends than me, we talk on the phone like once every 2 weeks, we text in the morning than I don't hear from him until 11 that night. He doesn't see me between cles, or barely walks me to my bus. This week he was freaking out because he had work and stuff but owed 9 current event articles in Am Gov Friday, and he asked if I could help me with them so despite my heavy work load already, I did 6 of them because I want him to graduate with our cl. I emailed them to him last night and sent him a text letting him know they we're there and I love him, attached a little funny video and everything. So I'd expect since I wake up an hour after he does that he'd text me say thank you or something. He didn't. I was close to cussing his azz out but I didn't. We texted a little and I was trying to put that behind me but then he just did the normal and stopped out of nowhere at like noon. Later he's going to say he couldn't talk and when he got home he went straight to sleep. He can't just spend 20 seconds and let me know or something? I stayed up until 3 last night doing our stuff combined. And tonight he's going out to clubs and stuff and I'm not allowed to because my parents are being... ugh. But I don't know, wouldn't you be upset? I feel really sad that he's treating me like this... and I was hoping maybe he'd just spend today with me.
