i need advice ..

so I have a spending problem but I also know how to manage my money and my bills so i’m never living paycheck to paycheck .. my boyfriend on the other hand gets paid on a thursday and it’s gone by monday .. he wants us to move out to get a place but doesn’t understand that he needs to save money and thinks we can do it right now .. anytime I offer my advice on how to save his money he gets so defensive with the “I know” blah blah blah yet he calls off work atleast once a week .. I love him so much but I don’t know what else to do or say .. any advice?
