Are you and your family okay? Yes, it's a new day and it's time to start by going NC. NC will help you find your balance and your focus, which should be on you, your unborn child and your children. Of course, right now, you are looking at a clean up later in the week into next week. Worry about that chore when the weather is better.
Your h does feel guilt and shame and it will only get worse as he continues moving forward on the mlc path. He is angry at the world and is lashing out at you. It is not your job to build up his self esteem or make him happy. He is the only one that can do those things and I would venture to say that his parents or someone in authority didn't do that when he was a child. He is definitely acting like a teenage bully.
Step away from his drama. If he texts about the house, yard or the welfare of the family, you can respond, but other than that...don't. You do not need to be bashed over and over again by him.
Sweetbriar, you can't fix him because you didn't break him. Right now, he's trying to break your spirit to get what he wants. Stand up straight and hold your head up high...you've done nothing wrong and are still standing for your marriage. He's the one that walked away and should be walking around w/his head down and his tail between his legs.
Today will be a better day....go NC for your well being today.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
