I'll try not to make it too barftastic.
We had fertility test as we could not concieve, over several years. My dh got the diagnosis of complete infertility (therefore his dd from a previous relationship was not 'his') and we were not able to have children.
My dh wanted to go ahead with a sperm donor, which we did. He was fantastic through the process, we attended all appointments together, he held my hand during the excruciating painful bit, and we had dd.
I was poorly after a horrendous 25hour birth, large bloodloss and emergency c-section. Unable to breastfeed 
Dh did every night feed with dd. Every single one. He packed me off to bed a 9pm, stayed up until 6 or 7am, then woke me up and we switched over, he would sleep for 6 hours and then go to work until 7.30pm. He clearly adored dd and never moaned, not once, and never made out like he was doing me a favour.
Even though she isn't biologically his, dd and dh are very, very close. She burps like him 
and they are two peas in a pod 
.
In the past few years, my physcial and mental health has taken a nosedive, I've had addiction problems with sleeping tablets and painkillers, and my dh has been with me through it all, despite coping with plenty of other things on his plate.
Recently he has found out that because of my crap mental health, I have managed to get us into large debts without realising I was doing it 
and our financial future has dreastically altered because of this.
He has never once shouted, accused, blamed me, or stormed out. His reaction was shock, then a huge worry about me as he felt I would not be able to cope. He has taken dd to school every day since I got ill with depression (on ad's for 2 years) and done homework with her, played with her, bathed her, ironed, washed up, done laundry and cooked. For at least 80% of the time.
He has never hinted that he is 'helping' out (although he is helping the whole family out!) or doing me a favour. He has just got on with it, with never a cross word.
Due to my illness and other ishoos there has been precious little, erm , actually doing 'it' in recent years but he has never pressured, moaned or complained.
I love him so much my heart could burst. If I could, I would give him the best bj in the world and then cook him a sunday roast. I can probably sort out the sunday roast...
I jsut wanted all ye women who have been treated badly, been in abusive relationships or who have just ended thinking 'all men are like this' that that is not the case. At times he can be a nob end, but, well, he'll do.
Can we clone him? He's got a big nose though, that a problem for anyone?
