My boyfriend seems to think I distance myself from him and am acting flaky. He gets panicky whenever I get distracted and dont talk to him for a while, or talk to him exactly when I say I will. I feel it's not good for his heart as he has a heart condition. I also feel like its a bit smothering. How do I get him to relax a bit and find a way us to find a happy medium for communication?

I feel we will be better when he flies over here and we don't have a 6 hour time difference it'll be easier.
