Yes, it's hard.
the hardest part for me was the early years and the sleep deprivation. I took the full year mat leave with dc2 and still, when I went back to work, the sleeping thing was a daily grind and I remember sitting on the stairs sobbing, hungry, desperate. (no help from P who clocked off the second I walked in the door)
Things are better now. They are 5 and 7, love school, I love chatting with them about it, I love that they have independent lives and do things without me and then tell me all about it.
ExP and I are separating. Despite the fact that he will never have any idea what maternity leave with an EBF baby is like - or with an EBF baby and a toddler - he bears a massive grudge against me that his life is so duty-orientated and that he has so little freedom. (He has no fucking clue.) I commute and he doesn't so he does do some childcare when I am not there in the evenings. However, he does it sloppily, lazily, and bitterly resents me for it although my 13 hour days are hardly a picnic (and necessary for the finances of the family). We both agreed to have children and he was more into it than me, if anything, so I am not sure why he thinks that I, as an individual, am to blame for him not being able to wander off to the pub at will. He also suggested that we move here and that I commute to work so I am not sure why the reality of that makes me such a bitch.
I said it was better and it is - partly because we are separating. Although I am very sorry about the initial sadness that this will cause the dcs, I am happy that I can live my life without being under the constant shadow of guilt and resentment because of his attitude to the situation. AND he wants to have 50/50 residency and I agree. I am sorry that I will lose control over some of the things that he can't be arsed to do some of the week, and he has taken the easier part of the week (and arranged for his mum to do all the school pick ups).
But that life of being howled at, kicked, and kept awake all night by children, AND earning a living in a demanding job AND being glowered at by the man you live with because he seems to think your hollow, boring, empty, miserable, drudgery-ridden life with no calm, no rest, no art, no creativity, little comfort, little sleep, no personal space and eating rushed awful food ISN'T MAKING YOU QUITE MISERABLE ENOUGH - yep I'm ready for that to end.
