Help what should I do? Is he manipulating me?

So to start off my bf and I have a 4 month old together. Ever since I got pregnant I noticed things changed, our pregnancy was unplanned but he quickly adjusted. Ever since then I've been constantly feeling like I'm mothering him, he never just cleans up after himself, or takes care of certain things. I have to be the one to constantly tell him to do things otherwise they would literally never get done. Now that we have a baby I feel like I have two kids. My bf and I are in our early twenties I have been on my own since I was 16, he's never learned how to budget or clean up after himself and it's infuriating.. I feel like I've tried everything and it just seems like it's getting worse. We literally just had a talk the other day about how I feel, it was good the next day but then boom, right back to shit.. I understand that he isn't happy about certain aspects of his life, I've tried to help him, I've tried to support him. I'm just at a point where I feel like he's bringing me down. I've been going out of my way for him. I make him breakfast and coffee in the morning, yet he still tries to sleep all day (he works evenings, not overnight). I feel like I'm dragging my teenage son to school.

I work from home, and my baby is unusually needy. otherwise I wouldn't expect as much from him (although I feel like I only ask for things he should already be doing) I have no problem doing house duties, but not if he's going to be disgusting by leaving nail clippings on the counter, treating the bathroom and our entire room like it's some huge closet for him. I can sometimes hardly walk into the bathroom without having to shove his clothes aside or trip on a pair of shoes..

I told him I feel like he does the bare minimum to get by in our relationship but he disagreed saying he does do things.. Sometimes he'll cook dinner, he'll get up with the baby when I ask. But nothing really beyond that..

I don't feel any romance anymore because he's so cold and doesn't address my concerns. I still felt unsettled after our talk, it seemed like he knew exactly what to say. I mentioned I wanted to break up and he made me feel like I was being dramatic. He rocked our baby to sleep and said "see wouldn't you miss seeing this". Whether it was a joke or not I still feel like he manipulated the situation. There isn't ever resolution he just says he'll try, he says "I've just been having a hard time lately", then things never change.

On top of things he doesn't have a plan for our future let alone his own. He says he wants to move out of his parents and get married, but takes no steps forward. We can afford to save money and get our own place, but he blows money left and right.

I'm going to stay a week at my family's house for the holidays. I'm scared that he's going to go out and drink excessively, rather than working on the things he should be doing. He's been "studying" to get his real estate liscense and with us gone it should give him time.

I don't know what to do anymore.. it breaks my heart thinking that I might just have to call it off.
