It's funny. I'm dating my husband who has filed for divorce. WTF?
I'd say it's strange but around these parts anything goes.
Just be careful ok. The more you push for an answer about the filing the more likely you are to get some jacked up answer like "I don't know" or worse. I know how hard it is to have that hanging over you. I can only draw from my experience, but I definitely saw the more I pushed, the more crazy it got. I think my ex liked having that control as far as the D went. I gave her part of it too by constantly being concerned about it.
Keep living and enjoying life, and keep showing him a better you.
