Please someone help me!!

I'm really at my waits end. I thought me and my SO had pretty good communication. And we talk about everything. I've talked to him about helping me clean, asked him, told him, begged him and everything in between, countless times. And to no avail, he leaves a mess everywhere. Like to the extent he won't pick up unless I specifically ask him to. And sometimes I will ask him to do something and instead of doing that he will do something else. An example: this Saturday I had my clinical, so I was gone all day. He had our 1 year old daughter, a friend over who brought his two kids(older children around 10-13). I asked him to do the dishes. I said, if you don't do anything else please just do the dishes. I get home, he vacuumed. I thanked him. Didn't bitch at him or anything. Because until recently he really wouldn't have even done that.

I feel so dumb about being mad because he won't pick up after himself. It's all left to me to pick up after myself, our crazy daughter and him. And I have tried so many times to get him to understand how it makes me feel. I'm staying home with our daughter right now, I'm going back to school but class is only on Sunday's (9am-3:20pm). I'm also still breastfeeding (hence the reason I am still home). I appreciate him being the only one working and literally do any and everything I can to help him out. Laundry, cooking and cleaning. I wouldn't mind doing them things really, the issue is he doesn't pick up after himself whatsoever. Like will make a coffee, and leave sugar/coffee spilled all over the counter and not pick it up. Takes his clothes off and meaves them on the counter/floor instead of putting them in the laundry basket. I just don't know what to do anymore. It really stresses me out and he just really doesn't care. I don't want to leave because of something so "silly", but what can I do to make it better? Is leaving the only way? I know these are all things I should be answering. I guess mostly I want to know if I'm not alone or if this behavior isn't acceptable. Sometimes I just feel like I'm to OCD. But for real, put your damn clothes in the hamper, a hole...lol.
