Now, let's talk about what to actually say during this conversation. Be kind, but also be honest - it's a delicate balance, but it's doable. Try to use "I" statements instead of "you" statements - it's less blame-y that way.
And, whatever you do, don't lead him on - it's not fair to either of you. Be clear and direct, but also be respectful. It's like ending a chapter in a book - you want to do it gracefully, so you can both move on to the next adventure.
Lastly, remember that it's okay to be sad or emotional during this conversation. It's a big deal, and it's normal to feel overwhelmed. Just take a deep breath, and try to be present in the moment - it'll be over before you know it.
