Space

My boyfriend and I saw each other on Sunday, it was great we had a great time together. The only thing was that he had 2 assignments due that night and he missed the deadline for them (was due 11:59pm and he wasn’t done them) & he told me that and I apologized cause I surprised him when i visited him, he said he wants to be left alone and how it’s not my fault. Yesterday I messaged him (thinking he’s prob over it) and I didn’t hear back all day, so I called him at night and he messaged me back saying he needs space and to give him his space. After reading that, I freaked out and immediately blowed up his phone, and had an anxiety attack cause he wasn’t picking up and kept declining my calls. I wasn’t able to think clearly but today morning thankfully I am, I sent him a message saying I need to respect the fact that you need space as you’re overwhelmed right now (hes in mechanical engineering so the work load is insane), every now and then I think he’s really mad at me for missing the deadlines, has anyone else gone through this ? If yes what did and didnt you do ? Thanks in advance xoxo
