His phone is more important

Seriously losing respect for my other half lately. His phone seems to be more important than his 3 month old son. I'm on maternity leave until January, I've been with my son not far off 24/7. I'm not ready to leave him with anyone but myself and my other half (sometimes). The World Cup is on so that gets priority. The other day we went out for a day at the zoo. He had the football on the radio the whole way home and that's fine because I like the World Cup too but as soon as we pulled up outside our house I was left carrying all of the bags in, he had the car seat. As soon as he got in he plonked the seat down not taking baby out and put the tv on so he could catch the rest of the game he was listening to! Then when that finished he was constantly on his phone, our little boy with me (again) smiling at daddy who isn't even looking. I'm getting fed up with it. He's out tonight again to watch the footy with his mates for a few hours. Our son has started throwing tantrums a lot lately. When I said to him if he kicks off during the footy you're coming home to help me...his face was pure disgust. We share a mortgage but I wish I could kick him out sometimes.
