I'm terrified of falling in love with him
That's interesting. Is there a reason you are afraid of falling in love?
I'm afraid that I will get hurt.
I know that fear can be compelling, but letting it run your life ruins you and makes you feel hopeless. Confront your fears when they come up and push through them.
I'm going to block you so that you can't talk to me anymore. You give bad advice.
It's perfectly okay to not want my advice, and I'll certainly stop giving it to you. But, you don't have to be rude about it or block me. If you would have just asked me to stop giving advice, I would have gladly done so.
