Okay I need help...

Madison • beautiful Washington State! 2 Crazy boys with hopefully a third baby here soon! ❤️
So our son was born on Monday July 18 by induction, and my SO has been so excited to meet him this whole pregnancy and as soon as he was born my SO left the hospital shortly after his birth, and he didn't stay in the hospital with me not once, and he got mad because my mom held him before he did but that's because he left the hospital and she has Been the one helping me out this whole time with our son, and we finally came home on Wednesday and he has nothing to do with him he has only held him once for about 5 minutes, he doesn't get up with me at night, and he sleeps all day until he goes to work and then he stays out till about 6:00 or 3 and then comes home, and he doesn't wake up till he has to go to work at 5:00pm the next day. I try and wake him up and tell him to come be with me and his son, and he just says no or he just doesn't wake up. I mean he has missed his sons first week of life, my mom says that I should leave him and tell him to move out since he isn't gonna ever help take care of his son or be involved, and I have given him chance after chance after chance, and I love him, and we were perfect and then our son comes along and he wants nothing to do with him, I just don't understand what father doesn't want to hold or touch or have anything to do with his newborn. I need advice very bad... So please please help me.. .
