I need to vent for a min.

My baby daddy/boyfriend is typically a great guy. But lately he hardly has relationship with our baby, and he hardly seems to care about anything but what hes into. For example he has no idea what our babies routine is. I've kept the same routine for the last 8 months, havent changed it drastically, but when I did change things I would let him know. He doesnt know where the baby clothes go. Hes never given our baby a bath, and if our son cries he just let's him cry instead of trying to figure it out. And since it's our sons first Christmas I asked him to decorate a tree with me, and then wrap presents and he told me no and just stayed absorbed into his phone.

If I ask him to do something with ME he complains and tells me he doesn't want too, but if one of his friends ask him to do something he'll drop everything to go with them.

I've tried talking to him before about everything and how I feel and all he says is "okay"

I don't really know what else to say to him. But at this point I feel more like a single mother because he literally cant do anything for the baby when he needs it.
