Relationship feels rocky

Since I got pregnant we only had sex twice(his decision) now I'm on full bed rest as my cervix started thinning out. Dr said there's only 1cm holding him in. Bf said he prefers I'm home than in the hospital he now sleeps,on the couch and barely speaks to I reaching or should I be worried? I'm worried and attempted to speak to him on it but he just gets defensive saying I'm over reacting that nothing is wrong but he's downstairs on the couch watching TV and on his phone til he falls I crazy and want too much attention? I feel really lonely questioning our future.
