I'm not a vet but I want to remind you that while W has OM, you shouldn't be fulfilling her needs AT ALL. Let her get all that from OM. You need to protect your heart because her letting you rub her legs a little is giving you hope and that might not be healthy. Don't let her lean on you so much. I know that's easier said than done but you're giving a lot... and she's taking a lot.
