Space

So my boyfriend came over yesterday and we had a amazing time until of course I ruined it towards the end. It was 2 days before, I had got upset because he was ignoring me and I hadn't heard from him in probably 5 hours, I was worried and anxious but I also had things going on personally that had made me anxious and I just needed his comfort. So I decided to call and he didn't pick up. He called me back a few minutes later and was just short and distant so I just stopped talking and was trying to process and just trying to figure out what I can do to help him or if I had done something and he said that he had to go so I told him bye and hung up. That night we called again and I told him that and how he made me feel and he just said that I aggravate him whenever I close off because he has to go. I didn't close off because he had to go, I closed off for how he was acting towards me. He said I do it everytime he has to leave.... well guess what I did yesterday. It was the first time I had seen him in 2 weeks, I hadn't heard much from him because he has such a busy life. I just missed him a lot (plus being on my monthly thing I am more emotional) I just didn't want him to go so soon. He got upset with me but told me it was okay and that he understands... but this morning he called me and he was short and distant again and he acts like he can't stand me. I don't know what to do. I just feel I need to give him space but if I do that he's going to be upset. We both have a lot going on in our lives but I never fail to remind him that I'm always here and that I love him. Anyways how do I give him space and not feel defeated? I just feel like he doesn't want me around right now and I dont want to feel down the whole day because of it.
