My boyfriend is loving and caring and in all ways a helpful human. He occasionally needs alone time. Usually when this happens it means plans are changing which is a big struggle for me. I tend to get anxious and upset which can lead to me crying and draining his energy which I don't mean to do. He feels as if I get upset everytime he needs alone time and it isn't fair. I completely understand where he is coming from because he is only seeing the reaction. I get upset because plans change, not because I want him to overreach and only put effort into me. Although I am incredibly curious. What is the appeal to alone time? If I had the choice of spending time with him or I being alone, I would  chose him every time, despite being exhausted. Overthinking that makes me feel as if I am not enough for him. I also have a problem of over explaining how I feel to him and explaining all thought processes and triggers to reassure him that it's not TRULY about the alone time. I think the way I say it seems like an excuse for my actions though. Any inputs? Thank you so much.
