Peaked out of tunnel but now back in?

[mlh78]

Unlike me, you guys are so level-headed... I love it! Everything makes sense in theory but, here is where I get messed up:

This morning, I got an email from H asking to borrow some camping equipment for next weekend. Honestly, I don't want to lend him anything (rarely returns stuff--sometimes I wonder if he "borrows" stuff so he doesn't have to negotiate for it in the divorce).

He keeps saying things like, "I may be naive, but I don't think that getting a divorce means we won't be in each other's lives." I don't want to feed into his childish view that we'll be "great friends" after we get a divorce.

Should I lend the equipment to him? Should I politely say "no"? Or just ignore the email altogether? It is hard to "go dim" when my H keeps popping up, usually about little stuff that keeps us talking/communicating...
