I don't have the strength of character to walk away.
Seriously? There's not a person here that believes you in any way lack strength of character. You have it in spades.
So let's imagine you say it, he doesn't love you back, and you don't walk away. A year or two ago this might have been concerning. Now, it's a choice, not a character flaw. You are self-aware enough and have the right boundaries in place to make an intelligent decision whether this is a situation you'd like to live with or not. Give yourself some credit here, Maybell.
