Feeling like a failer

So I guess it's to much to ask for any help from my daughters dad. She is almost 2 and I have one die in march but if it's not putting her to bed or down for a nap I'm on my own. I get told I'm a horrible person and he should go back to California. And I'm to the point that I dont care. I'm told I'm nothing but an attitude and his attitude is more like I'm the man you do what i say. I understand I'm not perfect but it seems as if since he started talking to his sister in law things have gotten worse. She tells him he can come out there for a couple months and that he can get an apartment. So what am I chopped liver. I sometimes feel that if I dont bite my tongue then I could be in deep trouble. I can't leave as that's not an option. How do you all do it. The sad thing is I love him so much which makes it worse
