Baby's Father

So I'm 16 weeks and before I got pregnant everything was good but now it's not and I told him its best to raise this child together but separate. I want him to be a good father I know he can be but we aren't working out theirs no mutual respect and I'm tired of everything being my fault when I'm trying despite all signs saying give up. I cried so much today in physical drained and after he said I was an incovience I just told him sorry and that we shouldn't be together then. I am I making a mistake should I still try to be with him. Is anyone else not with the father?
