This will be long. I think I know the answer, but would appreciate the outside perspective.
Married 5 years, together 7. We have 2 DCs, 3 year old and 4 months old. We both work in professional jobs with good incomes, I am now on maternity leave with second DC.
My problem is two-fold.
One is that DH leads a lifestyle of a child less man, while having 2 planned kids. Yes, I wanted children more than he did, but nobody held a gun to his head when we were making them. Outside of nursery (while I am on mat leave older DC going to nursery two days a week, then it will be full time once I go back for both), I do all of the childcare for both children. He hasn't changed a single nappy since #2 was born, in fact he doesn't pick #2 up when he cries. 'he wants food' <I am breastfeeding>
DH's idea of disciplining is through shouting. In fact, every time I leave the room there is a 90% chance he will shout at DS(3) 'to discipline'. DS(3) is your average 3 year old, there is no out of ordinary challenging behaviour.
I do all bath times and bedtimes. I don't think he ever read a book to either of them. As a result DS(3) is not bonded to him. The only time DH spent one on one time with DS(3) is when I was in hospital having #2. He also does minimal housework, but is a messy person.
I knew he is not exactly the dad of the year when going for #2, but he didn't really shout when we had only one child and he had better mood.
This brings me to his personality. For past several months constantly irritable, he is always moaning about something or annoyed at something. Walks through the door and starts complaining. In addition, something always hurts. It's nothing major, a sore finger, or a headache, or a random pulled muscle etc.
He is glued to his phone All. Day. Long. While I am running around keeping the house going and sorting out two kids, he is on the sofa on his phone, no matter if it's bedtime, bathtime or apocalypse. More often than not I have to say things twice before he registers I am addressing him. It's really wearing. I find it a lot easier when he is not at home. Needless to say he never did any of the night wakes for any of the children.
I am tired. I am really annoyed he shouts at DC(3) and does literally nothing with DS#2. His constant moods are a drag. In turn I just shut down and focus on the kids. I try to be a more affectionate wife, but all of the above makes my undercarriage shut tight.
His good qualities are: he is very intelligent, interesting conversation (when he bothers, that it), very loyal, hardworking.
So, my question is, do I keep trying to do something about the above or do I call it quits and separate?
In case of separation, he would probably push for 50:50 which would break my heart.
