Not getting on with my partner

I'm really fed up and feeling tearful. When my son was born almost 12 weeks ago, my partner and I felt closer than ever. Right now I feel like we couldn't be further apart. He works away Monday to Thursday and then is constantly on the go when he's home. I don't care that I do everything for my son 7 days a week but it would be nice if he considered  us a little bit. Am I alone feeling like this?
