<human>: You can catch up on our background here: 

Mark and I need to end things.  Things have only gotten worse, not better, and I can't take the daily pain - emotionally, and physically due to the anxiety about it.  But he refuses to see me in person (we did go to lunch a week and a half ago, and things were "okay") and ignores my phone calls, too.

Even if suddenly he changed, and became more committed to communicating, and stopped hiding things (aka lying) out of fear, I am too hurt right now to be able to trust him.

I can't bring myself to send him a text.  At this point, I just want to have a brief, positive, candid conversation and wrap things up as best we can so that when we each reflect back on this in the future, we have a mildly positive last memory of each other.  More for me than for him.  What do I do?

Give me a shortened version of the text
<bot>: Boyfriend won't see me or pick up the phone when I call.  How do I break off our relationship respectfully?
