donno why

I don't know why he always says I give him the pressure.
He wastes his time during the day time to sleep or to chat with his friends.
As a result, he doesn't have time to share what happens during the day to me, because he has to study.
If I say: please try to use the day time and to spend the evening with me, and he will say I give him pressure.
In my opinion, we can't spend time with each other during the day time, so for sure, I hope we can spend some time in the evening.
Am I wrong?
In spite, I told him that I feel sad because I didn't have any progress in my German.
The response which I have got is that I give him the pressure.
I spent time to correct his Chinese but he didn't spend the time to teach my German as long as mine.
I even have to post a notice to look for the language exchange.
What a shame for me...
Everyone asks me why I have to look for another one.
I have already had the one who can practice German with me.
I don't know why.
He says he loves me so much...but I don't know.
He said I bothered him a lot because I sent him 10 SMS someday.
It's just because I missed him.
Anyway, as long as he feels stressed, he starts to challenge me everything.
That's him.
