Homophobic mother

Hi I posted last week about my girlfriend wanting me to tell my homophobic mum about us on Boxing Day.

Anyways she got sick and I obviously I couldn’t go to my mums house with my 1 year old cause I wasn’t going to risk her getting sick. She got A bad flu was bed ridden and still is not 100% well.

When I told my girlfriend mums sick, she said I better make sure I still go.. and I said but shes sick.. so she cracked it at me and gave me the silent treatment legit all weekend. It was the shittest weekend off with her. She barely spoke to me, and was shitty at me all weekend. Like I could change my mum being sick.

She made me feel guilty about it all weekend. To make things more complicated she proposed to me on Christmas Day. Which I was totally shocked about... to make me feel even worse about it. I don’t know why she did it but I said yes cause she did it infront of her family ..

My mum still isn’t well, and she cracked it at me lastnight and barely spoke to me about it. What should I do?
