How would you feel?

I work and do this with both kids, he also works, I get very little time to see my friends making the main adult I talk to in my life my partner. He sees his friend around 3-4 times a week. 

I feel so down about the way he is with me, il call him in the day for him to just be off with me, It feels like I constantly get on his nerves by just being here, he takes everything I say the wrong way which usually results in him telling me to just go away or f**k off. We don't really talk much when he's home. I get up with the kids every single morning, j bath the kids, if I ask him to it sometimes turns into us bickering. He very very rarely takes them out by himself. 

I told him how I felt today and asked for a bit of space, he said 'fine but don't expect me to come back when you want me too' I told him I get really unapriciated and like he doesn't care, his response 'we've been together 8 years people change and it's understandable ' he will sometimes help me with my job but only because he'd rather do that than watch the kids so I can do it. I don't know what to do anymore, I have no one else to talk to.
