<human>: I am ready to break up. The feelings are not there and it is not fair to lead him on.

My dilemma is that I tense up, start panicking and go mute when I have to have difficult conversations. I physically get so anxious that I can not make myself talk. I wrote down what I want to say, but I can not muster up the courage to actually say it, either in person or on the phone. I am psyching myself out and feel like a complete coward because I am actually trying to rationalize how it really isn't that bad to text him. I know it is. It is disrespectful and immature. I just can't make the words come out. 

Any advice?

Can you give me the gist of the text in a nutshell?
<bot>: My anxiety is getting the better of me and I am trying to talk myself out of breaking up with him via text.
