Please check my grammar, mistakes and logic! Thanks a lot!

I asked him if he could help me to prepare an audition and he told me he won’t help me to do any audition now because I’m not good enough for him so far. Even if I go to the audition by myself and win the job, he won’t admit that I’m one of his students.

His opinion is okay for me.

And then he asked me to cook dinner for him at my place after our next lesson next Monday and he suggested we go grocery shopping together.

I told him it’s too difficult for me. I’m afraid to screw it up. To cook for you is more difficult than to play for you. He said I’m going to eat your food not you. You don’t worry about it. I said I’m nervous. He said if you don’t want to cook then I can take you to a restaurant and we have dinner together. (Yes, he didn’t say to invite me.) After our lesson, he left me a voice message, his way of speaking was extremely soft and weird. He is so different! (I felt uncomfortable.)

Things came to me so sudden and I was too shocked to have any reaction. It took two days for processing and then I started to feel angry and anxious.

It forced me to make a decision right now: to move to Poland for studying or to go home.

It’s my last time to give a try in Europe so I decided to move to Poland.

How will life be in Poland? I don’t know. I’m both looking forward to it and tired of changing my life again. How can my feelings become so complex? Will I be happy or lonely ?

No matter happy or lonely, it’s life and I have no choice to be brave.

When life gives a challenge like this, I can only accept it gracefully and smile confidently. Wish myself all the best and focus on my study with my original passion.

Good on you, it is a shame but I am glad you are not letting this crush your ambition. We have an expression, 'Sticks and stones may break my bones, but words will never hurt me.' Kind of means to toughen up and don't worry what people say, which can be hard sometimes. Good writing, clear and easy to follow.

His opinion is okay for me. Or 'I can accept his opinion.'

And then he asked me to cook dinner for him at my place after our next lesson next Monday and he suggested we go grocery shopping together.

I told him it’s too difficult for me. I’m afraid to screw it up. To cook for you is more difficult than to act? for you. He said 'I’m going to eat your food, not you. You don’t worry about it.'

I wish you all the best too. Sorry to hear about that unfortunate incident.
