No starmoon, I remember you exhausted with the childcare, housework etc and you would have loved for him to have been more hands on but he was too busy discarding you. It was a good excuse for him. He blamed you, then used this as an excuse to discard you then he was free to rest and relax at his mums while you had the responsibility of the care of the children, house etc. Abusers always like to do the least amount of the hard grind as possible even though they may give the appearance that they work.
You would have loved nothing more than the two of you to have been pulling together rearing the children, managing the house, cooking and shopping together. But he didn’t want any of that, so he would storm out and leave it all to you.
Not your fault.
