losing baby/thanksgiving

Recently married and 10wks pregnant and going through hard time diagnosed with threatened abortion my husband has alittle 3yr old and has joint custody wants us to go spend the holiday at his sisters we where also invited to my family’s we was gonna hop around I guess instead of do our own little thing too but yesterday the baby started passing and I just need to rest I’m not in no shape for any event or cooking cleaning and walking around or being by people he’s not an understanding man how do I tell him I don’t want to go need to just rest. I’m making two pans of lasagna and was gonna send him with it to where ever he goes I just don’t thing I’m up for it I feel bad but he is gonna be so angry and he is already insensitive to me losing the baby.! Doesn’t ask if I’m ok how I’m feeling nothing.! I told him I needed to rest yesterday he left me alone with his son till midnight when he wants to walk through the door.

Honestly idc about thanksgiving wtf I gotta be thankful for
