What do I say to him?

I am meeting with my ex partner on Monday to discuss moving his things from our shared home. We were together for 2 years and lived together for the last 7 months before he discarded me. I feel my entire world is shattered. I truly saw my whole future in him. Part of me knew my needs were not being met, but I was patient, loving, and willing to work through anything for him. I want to protect myself. Part of me knows I can never take him back, the other part of me wishes he would just come home. How can I go about this process with the most self respect and kindness to myself?
