So we first met at a party, ended up making out, that was it, I just kind of didn't think anything would come out of it, and wasn't about to get my hopes up. but he ended up messaging me the next day on facebook, we talked there, then he found my note with my number on it, and started texting me, then he added me on snapchat, and we talked there.
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
