No one is sick of your posting. You're experiencing a loss and we are all here for you.

Why don't you send him this post, exactly?

So he can understand?

I totally get you rejecting what he was offering because you were trying to defend yourself from feeling any more hurt over this.

If he is as kind as you say, he probably will understand that too. (at the same time though it might still not be possible for you to follow him to wherever he is going...)but I think you should still ask. All he can say is yes or no. You have nothing to lose bc he is already leaving, but maybe something to gain in case you can work it out somehow? I know this must be so hard for you. hang in there, you can make it through this.
