We started hanging out, we're in similar majors and I had already taken a bunch of the classes he's in, we just both have calc 2. At hangout number 7 (april 15th) I slept over (we had planned this after the one before this) and we Just made out, and I slept over we also talked a little bit. Then I went over there at 4AM on Saturday night (april 18th) (I strongly debated this one, but I knew he was busy this weekend so I did, I also wasn't going to do anything I didn't want to do) and we just made out and I slept over. the next morning he said maybe I could come over later (his mom was in town so I figured this wouldn't happen)
So we haven't hung out in about a week and a half. Before he would ask me if i wanted to come over and we would usually just work on homework, and sometimes watch netflix after (his roommate was always there, so it was just hanging out, nothing happened) I asked him to hangout last Wednesday and he had to finish a lab report (this was legit, these lab reports are 20+ pages and he had lab the next day), so I asked about Thursday and he said he was going out with his friends (which was perfectly fine he's allowed to have friends).
then last night I asked him if he wanted to hang out and he said he had to study for a final he had tomorrow (today) otherwise he would. So I asked him about tomorrow (today) and he didn't respond for 4 hours so I texted him and said "I'm just going to take your silence as a no" and he responded, "I'm just trying to study for my test sorry" and I said "Sorry I know you're studying and I didn't mean to disturb you, it had just been a while and you didn't answer.
What I really want to know is If I'm justified in asking him whats up with him, and why he's kind of been distant... I honestly haven't done anything I feel like is wrong... and when I talk to him in person he's friendly and everything. I just want to know whats up
