<human>: So I've been together with my boyfriend for only a short 7 months, but we've had an intense relationship and fallen very hard for each other. We both are on the same page in knowing that this is a serious relationship and we have long-term plans including cohabitation coming up soon (we will move together when he is stationed for military). He's in engineering school so I know he's sometimes busy and overloaded. I lost pretty much my only friend I ever see over the summer and he was also my roommate so I have noticed myself that I've moved a lot closer to my boyfriend, interacted with him more often, etc. I'm not used to living all alone yet and I know I can be clingy at times - and I'm working on that. 

Last night, I was just making small talk through text when he really snapped at me - saying he can't concentrate or get anything done with me talking to him every 5 minutes. He was studying and working on a paper at school and I wasn't aware that he was staying later than when he said he would be out, or I would have let him study in peace. He said "sorry, maybe I'm just tired and disoriented."

That was 10pm last night, and he ignored me all day today (I sent an apology for disrupting him in the morning and asked if he was feeling alright around 3pm). I left him a voicemail at 6 to say I was worried about not hearing from him since last night, and to get in touch when he has the chance and he just said that he doesn't feel like talking. 

I realize that he snapped on me because I was (even unknowingly) getting in the way of his important paper. I'm just confused why it has still carried over to the next day. 

Knowing the backstory now, am I being overbearing, Reddit? Does it sound like he needs more space, if he does how can I change my ways to come off less clingy? What should I do/should i have done differently?

Can you give me a shortened version of the text?
<bot>: I think I may be a clingy girlfriend. My boyfriend hasn't wanted to talk since getting irritated with me last night (extremely unusual for us). How can I change? Does he need more space?
