<human>: Hi.  My boyfriend is studying abroad in Japan.  Before he left he was a really sweet and attentive boyfriend, always sending me messages like "I love you" and stuff like that.  Always responding nicely to me.  He said stuff like when he goes to Japan he will buy me presents and he can't wait to live in our new dorms right next to each other next year.  His behaviors were never ever sketchy or seemed like he didn't like me.

Then he goes to Japan.  It was a really rough transition for me because I went from talking to him every day to about 5-15 messages a day.  Transitions are especially hard for me because I have Asperger's.  I realized I was monopolizing his time a few days ago and I've cut back my communication because he told me he's too busy to talk and I just send messages like "Good morning" and "good night" and "i love you" instead of in depth convos.

He keeps responding less and less nicely and never sending me anything sweet anymore.  He went to Japan with me in his profile pic on LINE (messaging app), and then he changed the pic to one of just him.  Today he added over 8 new Japanese friends and removed me as "in a relationship" on his public profile on Facebook.  While i was talking to him.  I just texted him about it asking why he did this but he didn't respond yet, i'm sure he's going to get mad at me for bringing it up though.

Is this behavior sketchy?  Am I "crazy" for being upset over it?  I love him and i want him to have a good time but I just feel so lonely over here and I'm not sure why he is doing this.  I also asked if we can video call every day and he said "tbh i never have time."   I guess it would be overbearing to ask him to make time for me?  IDK.  Please help me.

Can you provide a brief overview of the text?
