So what kinds of things can you do to make yourself more emotionally attractive?

Right now everyone is limited.

But, you state you discuss his hobbies. What are yours?

I would suggest joining a book club. When you can volunteer somewhere. Do outings with just you and the kids. Don't invite him. Don't be rude and if he wants to join in fine but he has to be the one sniffing.

I'm sorry there seems to be no forward motion happening... but time may be your best ally.
