c'mon connor, stop being more and more dramatic about this, there is a solution if you want to take it. give her comfort nights all to herself, no kids, no noise, no nothing...draw a bath, light a candle, put on soft music and then leave, do this once a week. she needs to de-stress. if you help her and talk about improving things (not pointing the finger at her i might add), focus on her. ask her what she wants. would she like you to give her a free night once a week, is there anything else. spend time with the newborn and tell her you think it would be good for you to start bonding with the baby. calmly talk. tell her the catch is....you love her and you hate this stress between you both and you want to sort things out so that you both can be happy.
calm down connor, i understand the stress and anger you are feeling. do you want your marriage to work?! if so then have a think about what i suggested.
