<human>: Can you give me the gist of the text in a nutshell?

We've been married 6 years, and I understand that a child changes marriage etc (our son is 14 months) but while my husband (who is a SAHD and works part time evenings and weekends) is 99.7% of the time a really great dad, there are certain ways he acts when he's tired (and with a toddler, tired is your natural state of being) that chip away at my love for him, bit by bit.

I am the main breadwinner, my husband went part time after I went back to work. In the beginning I was really happy with this arrangement; I'm a social person and love the adult interaction my job provides, but as time has gone on, I've become more and more resentful that I'm not the center of our son's life. Mommy is an afterthought for him. Daddy is where it's at. And again, I know that it's normal for the child to gravitate towards their primary care giver and in the beginning, as I said, this wasn't an issue for me. However, it's opened a whole can of feeling-worms for me. I'm not seeing my husband with the rose tinted glasses I once did.

He cares for our son at night during the week as I get up early for my job. He becomes easily frustrated and I hear him swearing at our son when he is having teething pain and not sleeping well and other things like that. He'd never physically hurt him, I know it's just him vocalizing his frustration, but hearing these things, I can almost literally feel my love for him drop away bit by bit. 

Now I see his lack of motivation, his laziness, his excuses. I was blind to these before because I was his motivator, I motivated him to get things done. Now that I'm feeling less than loving towards him, I'm not covering for him (per se) and the flaws are glaringly obvious to me and I don't have any idea how to fix this.

I've tried to force myself to get over it or turn the other cheek etc but it's insidious and once where spending time with my husband was the highlight of my day, now I look forward to him being at work.
