Frustrating husband when helping my mum through cancer diagnosis

I know I’ll probably explain this quite one sided but I’m really frustrated with my husband and I think he is being rude and unreasonable. My mum lives on her own about 40 minute drive away following my dad’s death 2 years ago following a horrific battle with a glioblastoma brain tumour. She has just been diagnosed with endometrial cancer and is booked in for a hysterectomy next week. We are lucky to have a couple of spare rooms at our home so I have said mum can come and stay with us whilst she recovers. I discussed it with my husband and he agreed but challenged how long she would be staying. His mum is due to be coming over from Malta to stay a few days after the operation (booked before my mums diagnosis). He has not checked that I would be able to manage having his mum in addition to my mum and my two young children who will be off for the summer holidays. Instead he’s concerned his mum would find our smaller spare room too uncomfortable as I’ve rightly said mum needs the space and comfort whilst she recovers. He’s now suggesting I go and stay with my mum for a couple of weeks, but that would mean being away from my kids. All because my MIL would prefer the better bed. I’m so upset this is his focus and not asking me how I feel about it all and that he will support whatever I think is best. I’m fighting to keep my head above water and just feel he's not even thinking about what I’m going through. He’s now sulking as I’ve said I don’t want to leave the house and my children. Am I being overly sensitive?? Thanks so much and apologies for the rant!‍ xx
