What would you do

Been ignored for 3days (we live in the same house) no support with our son at all in those 3 days, to top it off little one crying most night can’t settle him so my partner gets up out of bed goes downstairs and sleeps on the sofa. I just can’t deal with it anymore. I’ve tried talking to him before about wanting and needing more support, time, affection etc and if anything changes it last a week at most. Advice please. Really don’t want to break a family up but I just lost right now
