it sounds like your bf is being honest and straightforward with you. the vacation probably just made him realize how unlivable his schedule really was and now he wants to change that. do you journal at all? i find that a great way to get my emotions out so they are not bothering me. try different things to relieve your anxiety. get some exercise. get involved in a hobby you love, etc. of course getting to the root of your anxiety is always good too. i think it's all going to be fine so do try not to read things into what he says that isn't there.
