I am in a similar situation myself but still in the pondering stage. I am questioning whether or not my situation is emotional abuse.
My OH works full time (as do I) but does nothing with me or the kids. He puts himself first always, going to the gym, to see a physio, eating out etc. He doesn't go out with friends, drinking etc but is very selfish with his time. He stomps around the house when the kids are playing up, disapprovingly huffing and puffing because of the noise. He's slept downstairs for the last 9 months since my DS2 was born because of his night wakenings. He won't help at night, nor get up with the kids in the morning when I have been up in the night with them.
I can count on one hand the amount of nappies he's changed between them (my DS1 is no 2) and he has never bathed them or put them to bed. We don't do much as a family as he fills his weekends with the gym, trips our shopping or to get his hair done - anything that gives him his 'me time'. I haven't had any me time at all in the last 2.5 years...
Not only does he not help with the kids, he does nothing around the house but ALWAYS complains about the state of the house, the lack of ironed clothes and food in the fridge. My house isn't unclean or even untidy, it's just lived in with 2 babies as expected. I wash but I don't iron as I simply do not have the time or energy! I iron as we wear but he is precious about having all of his clothes neatly hung in a wardrobe to choose from.
I just feel like I am dealing with 3 babies rather than two and he isn't enhancing our lives in any way which is very sad to say.
If I choose to leave, I will have to do the same as you. I am not financially independent and so it would require planning and also, I don't want to disrupt Christmas for my family.
