need advice

Okay so my baby daddy and I have been together for a year and a half and have a 4 month old daughter together. My issue here is that, he literally never helps me with anything. He never helps with chores or takes our daughter off of my hands to help me relax he literally treats me as if he doesn't appreciate me. He takes everything I do for granted. I know for a fact If he didn't have me nothing would ever get done. When I was pregnant I worked full time and still did everything for him and for us and he still never did anything for me! Didn't help me once.  But the thing is he's not an asshole he's just immature and doesn't appreciate me. He's a year and a half younger than me but I've had these conversations about helping me and not being lazy with him since before I got pregnant. But I am so done feeling this way that I don't know what to do anymore. The only thing is that I would have no where to go if we split and I just don't know what to do. Have any of you ladies been through anything like this and how long have you dealt with something like this before giving up???
